The first part of the book of Exodus lives up to the meaning of its title – exodus means going out; it is about the plight of the Israelites in Egypt, the early life of Moses and the miraculous escape from slavery into the desert and on the way to the promised land. But then we read of the establishment of the covenant between them and Yahweh. But this is an account put together after much retelling, adaptation and development. During that time the rules by which the people should live became established and were put together in the form of a book they originated at the time of Moses and the Book is attributed to him ( Exodus 24:1-7 ). The first reading for today is taken from this book shortly after the Ten Commandments were given at Sinai. Among all the ways that those in covenant with God should live is this definite section about how to treat immigrants – foreigners living in your land. We notice also the strong image of God as a strict ruler who in anger will deal harshly with those who let him down. Ideas about God also develop with time.

The first reading is a very upbeat announcement of the good times that the Lord will bring about for all nations. This is not just about the freedom of the Jews who have been in captivity, but it is a universal message of good times, with plenty of all the fruits of the earth and no fear of troubles. The destruction of death might be seen by Christians as the announcement of life after death, but when this message was first delivered, probably in the 6 th century BC, it meant no more will enemies kill each other. All these wonderful gifts from God are, however, delivered to all peoples “on this mountain,” a phrase that initially refers to the city of Jerusalem which is centred upon and around a prominent hill in the countryside; though the phrase was used symbolically to refer to all the people of Israel. So we see in this passage the basis for a future view of what God will do for all people on earth, but with the restriction of it being centred on the people of Israel; it is the vision of a prophet who sees the future darkly, reading it from the worldly state of affairs that he interprets from the standpoint of his assured belief that his is also the god of those who share his faith. We know ourselves that many of us Christians are caught in similar limitations in our vision of God’s relationship with the whole world and its people.

In the first reading we have a very good illustration of a successful approach to delivering bad news when you are a prophet and that is your job. The book of Isaiah has been heavily edited, and our reading from chapter 5 is very likely the first public appearance of the prophet. If you want the crowd to listen to you, you don’t want to be known as a prophet of doom. So Isaiah draws a crowd by saying he is going to sing a song, like a street busker setting up his spot. It’s a song, he says, about his friend; it’s told as though it is about a man setting up a new vineyard, but it is really about unrequited love. He did everything one should for the vineyard to be successful, but it just produced (literally) stinking grapes. The friend then questions the crowd: “is there anything more I could have done?” And he tells them he is going to completely wreck the area and make it a wasteland. Then, when the crowd has grown and is listening intently, like a punch-line the prophet announces: “this song is about the Lord and you Israel!” The image of the vineyard became quite popular in the sayings of prophets and even among the people themselves; one of their hymns is the psalm that follows the reading for today.

The first reading is part of a heart-warming poem. It was written about the time that the people were going to be released from captivity by a friendly emperor, Cyrus. It attributes this release to the love of God, who has a special relationship of love for people, a relationship traditionally called a covenant. It is a two-way agreement: God will look after the people, and the people will live in a way pleasing to God. But the agreement is not conditional; it is not like God saying ‘if you keep my commandments I will be your protector and god;’ it is unconditional on God’s side: ‘I will be your God, so you will be my people however you respond to me.’ In the part of the poem we read today, the prophet is announcing to the people, God’s call to them; it is a call to give up any wickedness and turn their lives towards Him. But the prophet is also emphasising that God’s ways are mysterious, for He does not depend on the people behaving well for Him to love them and to be their God; there is no way they can deserve or merit God’s love, it is generous, free and everlasting. The extract is chosen for this contrast between God’s ways and ours, an idea taken up in the Gospel reading for today.

Reading Ezekiel we must remember that the Jews believed that they were the chosen people of the one and only God, Yahweh; they had laws and rules to live by and a covenant which they often thought of as ‘if we keep your laws, God, you will see that we prosper.’ Yet this arrangement didn’t seem to be working out in their history, especially when they were being taken over by a neighbouring empire. So much so that they began to think that they were being punished by God or even would die because of the sins of their ancestors; indeed they attributed all the difficulties and hardships of life to the original disobedience of the first humans ( Genesis 3 ), and they had a saying: “The parents have eaten sour grapes, and the children’s teeth are set on edge.” Ezekiel was trying to replace this idea with the fairness and mercy of God. Not only was God punishing the wrongdoer for his own sins and blessing the good, but saying that there would be forgiveness and blessing if the sinner repented and turned away from sin.

The reading from the Book of Sirach is making the wise and useful observation that God will deal with us in a manner similar to the way we deal with other people. So love and forgive others and God will love and forgive you. But if you… (you know what follows)

God speaks harsh words to Ezekiel the prophet. For Ezekiel knows the harsh things he should be saying to his fellow Jews, and that this will be for their own good in the long term. But who likes to tell others off? So God actually threatens him with punishment if he does not speak out when he knows that he should.

It's not so long ago that we were reading of Elijah wanting to die because of his failure to inspire the people and because of a death-threat against him. Jeremiah was in a worse situation in Judah around the 7th century BC. In that land, regard for Yahweh and the Covenant was almost entirely abandoned, and God urged Jeremiah to preach about the inevitable political demise and eventual national disaster. He had a respite from his work for a short time during the reign of Josiah; for this king tried to reintroduce the recognition of the Law of God as found written in what we now see as the early books of the bible, especially Exodus, Leviticus and Deuteronomy. But this reform soon failed, and idolatry and fertility cults regained popularity. Despite extreme reluctance, Jeremiah began the work of his calling, which was to bring him general disfavour, occasional imprisonment or confinement and continued unpopularity. There was some upbeat aspects to his message at times, particularly the one about God wanting to set up a new covenant within the hearts of the people. He suffered a tormenting turmoil in his own life; it resulted both from his natural abhorrence of preaching against his own people and from the deep and inescapable inner compulsion to undertake the vocation given him by God – announcing the people's downfall. Doing God’s will is not always an obviously good thing! Our reading is his outcry at this personal conflict within him.

During the time of the prophet Isaiah, the kingdom of Judah was threatened by the Assyrian empire from the east. Isaiah had recommended trusting in God to save the people and God would be with them. But the king and leaders didn’t see it this way, they felt they would loose, and forfeit their privileged positions, if not their lives. They made some sort of a pact with the emperor of Assyria so that Jerusalem was spared, although the rest of the country was invaded. So Isaiah, as we read today , reprimand Shebna the royal steward, and announced a replacement, who will be the leader to make decisions in the future; he will have the symbols of office, the sash, the robe, the key to the ordering of the country’s affairs, and will keep them safe like the peg for a tent. This passage seems to be in the mind of Matthew when he writes of Peter receiving the leadership office in our gospel reading. But the historical events behind it challenge us severely in our relationship with our world and with God, just as the sermon on the mount in the New Testament does: if anyone wants your shirt give them your coat as well, if anyone strikes you turn the other cheek, love you enemies… (see Matthew 5:38-48).
