The chapter begins by announcing that on that day the people will say: I will give thanks to you, O Lord, for though you were angry with me, your anger has turned away and you have comforted me. I will trust and will not be afraid, for the Lord is my strength and my song, and he has become my salvation. This first song is personal and acknowledges that God's anger, described in earlier chapters, has given way to comfort.
The next image is of joy: with gladness they will draw water from the wells of salvation. Water represents God's life and provision, which in the wilderness satisfied his people.
On that day they will also say: give thanks to the Lord, call upon his name, make known his deeds among the peoples, remember that his name is exalted. Sing to the Lord, for he has done gloriously, and let this be made known in all the earth. The hymn ends with an invitation to the inhabitant of Zion to shout and sing for joy, for great in her midst is the Holy One of Israel.
