In the congregation of the people; not only in their own hearts and families, but even in public assemblies, and before all persons, as they have opportunity. In the assembly of the elders; the magistrates or rulers; who are here opposed to the people. The sense is, Let them not be ashamed nor afraid to speak of God's wonderful works and praises before the greatest of men, as mean persons commonly are. Compare Psalms 119:46. Or he mentions the elders particularly, because they were most apt to neglect and forget God, and to exalt themselves above and against him; and therefore it was meet and necessary that they should be acquainted with the almighty power and universal providence and dominion of God, that they themselves might learn subjection and reverence to God, and might promote it among their people.
