Unto thee, O God, do we give thanks - We, the people; language which would be appropriate to public thanksgiving - showing that the psalm was designed for public use. The reasons for this public thanksgiving are stated in the subsequent part of the psalm.
Do we give thanks - The repetition is emphatic. The idea is, that the occasion was one for special thanksgiving.
For that thy name is near - literally, “and near is thy name.” The word name is often used to designate the person himself; and the idea here is, that God was near; that he had manifested himself to them in some special manner, and that for this there was occasion of praise. Compare Jeremiah 23:23.
Thy wondrous works declare - Or, “They declare thy wondrous works.” The Septuagint renders it, “I will declare all thy wondrous works.” The Latin Vulgate, “We will declare thy wonders.” Luther, “We will declare thy wonders, that thy name is so near.” Prof. Alexander, “They recount thy wonders.” The meaning seems to be, “They,” that is, the people, “declare thy wondrous works.” Thy marvelous doings constitute the foundation for praise - for the praise now offered.
