O give thanks unto the LORD; call upon his name: make known his deeds among the people.
Ver. 1. O give thanks unto the Lord] Some tell us that this and the two following psalms were the great Hallelujah sung at solemn times in their assemblies. But others say better, that the great Hallelujah (as the Hebrews called it) began at Psalms 113:1,9 ., and held on till Psalms 119:1,176, which they at the passover began to sing after that cup of wine they called Poculum hymni seu laudationis.
Call upon his name] Call upon the Lord, who is worthy to be praised, Psalms 18:3. See Trapp on " Psa 18:3 " Our life must be divided between praises and prayers.
