3. Reminder to thank God 136:26

This concluding exhortation contains a title for God unique in the Psalter. It highlights His sovereignty and was a favorite of the postexilic community (2 Chron. 36:23; Ezra 2:1; 5:11-12; 6:9-10; 7:12, 21, 23 [twice]; Neh. 1:4-5; 2:4, 20; Dan. 2:18-19, 28, 37, 44). Its occurrence here suggests a postexilic origin of this psalm though is does occur three times in pre-exilic writings (Gen. 24:3, 7; Jonah 1:9).

God's people should praise Him publicly by reviewing His great acts that prove His loyal love for them. This should be a part of their corporate worship experience.
