O give thanks unto the Lord (comp. Psalms 106:1; Psalms 107:1; Psalms 111:1; Psalms 136:1; Psalms 138:1). Call upon his Name; i.e. call upon him with prayer and praise, "according to his historically manifested glory" (Hengstenberg).
Make known his deeds (or, "his doings") among the people; rather, among the peoples; i.e. the heathen nations (comp. Psalms 18:49; Psalms 57:9; Isaiah 12:4).
