31. And the people believed. Either this is a synecdoche, a part of the people being put for the whole, or else Moses signifies that after the announcement was published, all with one consent embraced the message of their deliverance. I prefer the former meaning; because their solemn adoration is immediately subjoined, which could only have taken place in a public assembly. But we shall presently see how fickle and infirm was their belief. It is plain, from its levity and inconstancy, that it was without any living root. But it is not unusual that the word belief should be improperly applied to a mere assent and disposition to believe, which speedily passes away. Thus Christ (Mark 4:15) speaks of the faith of many as transient. “The people,” therefore, “believed,” when they heard that their afflictions were regarded by God, since that statement carried with it credibility and authority; but it was such belief as might be dissipated by the first adverse wind; and so, indeed, it happened. This passage, then, teaches, that theirs is no great attainment, and that they are deserving of no great praise, who eagerly and joyfully receive what is propounded to them in God’s name, unless faith, being deeply rooted in their hearts, sustains itself boldly against the assaults of temptation. Some connect the clauses differently, (65) “The people believed; and when they heard that assistance in their calamities awaited them, gave thanks to God.” But the copula is here rightly resolved into the expositive particle, and the sense is — “When the people had heard what Aaron reported, they believed.” God’s visiting them here expresses the actual occurrence, viz., that God was willing to render them aid in their sore distress. Their “worshipping” was in token of their gratitude, because it was not enough for them privately and individually to reflect on the favor of God, unless they also openly manifested their religious feeling; not as if God greatly requires outward ceremonies, but because they are useful supports to our infirmity, and it is right, that not the mind only, but the body also, should be employed in the service of God.
(65) As in A. V. ; and this rendering is confirmed by Dathe, “Hi fidem habuerunt; et cum audirent,” etc.
