Exodus 32:6

6.And they rose up early on the morrow. The earnestness of the people in the prosecution of their error is again set forth; for there is no doubt but that it was at their demand that Aaron proclaimed the solemn sacrifice; and now it is not only added that they were ready for it in time, but their extraordinary diligence is declared in that they appeared at the very dawn of day. Now, if, at the instigation of the devil, unbelievers are thus driven headlong to their destruction, alas for our inertness, if at least an equal alacrity does not manifest itself in our zeal! Thus it is said in the Psalm, (Psalms 110:3,)

“Thy (333) people (shall come) with voluntary offerings in the day
(of the assembling) of thy army.”

What follows as to the people sitting down “to eat and to drink,” many (334) ignorantly wrest to mean intemperance; as also they wrongly expound their “rising up to play,” as meaning lasciviousness; whereas thus Moses rather designates the sacred banquet and sports engaged in, in honor of the idols; for, as we have seen elsewhere, the faithful feasted before God at their sacrifices, and so also heathen nations celebrated sacred feasts, whilst they worshipped their idols in games. Of this point Paul is the surest interpreter, who quotes this passage in condemnation of the idolatry of the ancient people, and ably accommodates it to the purpose he had in hand; for the Corinthians had not gone to such an excess as to bow their knees to idols, but were boon-companions of unbelievers in their polluted sacrifices. (1 Corinthians 10:20.)
