Psalms 107:32

Let them exalt him also -Let them lift up his name on high; let them make it conspicuous. The word means “to lift up,” and is applied to praise because we thus, as it were, “lift up” God, or make him conspicuous. In the congregation of the people -Not merely in private, but in public. As his doings are public and conspicuous - as they pertain to all - people should acknowledge him in their public capacity, or when assembled together. And praise him in the assembly of the elders -The old men; the men eminent for experience and wisdom. Perhaps this refers to those who occupied some official position in public worship, as appointed to preside over that worship, and to conduct it.
