The chapter opens with a question: who is this who comes from Edom, from Bozrah, in crimsoned garments, splendid in his apparel, marching in the greatness of his strength? He answers: it is I, speaking in righteousness, mighty to save. He is asked why his garments are red like those of one who treads the winepress. He answers that he trod the winepress alone, and from the peoples no one was with him. He trampled them in his anger and trod them down in his wrath, and their lifeblood spattered his garments. He looked, and there was no one to help; he was appalled that there was no one to uphold, and his own arm brought him salvation.
From verse 7 the remembrance begins. I will recount the steadfast love of the Lord, the praises of the Lord, according to all that the Lord has granted us, the great goodness to the house of Israel. In all their affliction he was afflicted, and the angel of his presence saved them. In his love and in his pity he redeemed them, lifted them up and carried them all the days of old. But they rebelled and grieved his Holy Spirit, and he became their enemy and fought against them. Then he remembered the days of old, of Moses and his people: where is he who brought them up out of the sea, who put his Holy Spirit in the midst of them, who led them through the depths like a horse in the wilderness?
The prayer in verses 15 through 19 asks the Lord to look down from heaven: where are your zeal and your might? You are our Father, though Abraham does not know us and Israel does not acknowledge us; you, O Lord, are our Father, our Redeemer from of old is your name. We have become like those over whom you have never ruled, like those not called by your name.
