When it is said
Pray it whenever you want to thank God, for one gift or for all of them at once.
It also suits the end of a long trouble, when you can look back on what God forgave, healed and set right.
Where it comes from
Author by tradition
For thanking God in all things
St Athanasius wrote a letter on the Psalms to a man named Marcellinus. In it he says we ought to thank God through everything and in everything. He adds that when you want to bless God, you can stir up your own soul with this psalm and the one after it.
Sung near the start of the Liturgy
In the translator Isabel Hapgood’s 1906 service book, this psalm is the first antiphon of the Divine Liturgy, a psalm sung near its start. On great feasts other verses take its place. The same book also has it read at Matins, the morning service, as one of its Six Psalms.

The Scripture in it
Bless the LORD, O my soul; all that is within me, bless His holy name. Bless the LORD, O my soul, and do not forget all His kind deeds— He Who forgives all your iniquities and heals all your diseases, Who redeems your life from the Pit and crowns you with loving devotion and compassion, Who satisfies you with good things, so that your youth is renewed like the eagle’s. The LORD executes righteousness and justice for all the oppressed. He made known His ways to Moses, His deeds to the people of Israel. The LORD is compassionate and gracious, slow to anger, abounding in loving devotion. He will not always accuse us, nor harbor His anger forever. He has not dealt with us according to our sins or repaid us according to our iniquities. For as high as the heavens are above the earth, so great is His loving devotion for those who fear Him. As far as the east is from the west, so far has He removed our transgressions from us. As a father has compassion on his children, so the LORD has compassion on those who fear Him.
Bless the LORD, all His works in all places of His dominion. Bless the LORD, O my soul!
