Numbers 25:4

4.And the Lord said unto Moses. We have often seen before how God executed His judgments by His own hand, as if He put it forth from heaven; He now imposes this office on Moses, although it is evident from the context that he was not appointed to execute it alone, but that the other judges were associated with him; for it immediately follows that Moses intrusted the same charge to them, and thus, what was obscure, on account of the brevity with which it is recorded, is more clearly expressed. At any rate, it was a notable judgment of God Himself, though He employed men as its ministers. Nor does Paul in vain exhort (184) us by this example to beware of fornication.

The mode of the punishment, however, was diverse, for the lower orders were slain (by pestilence,) but the leaders were hanged upon the gallows, that the sight might awaken more terror; for by “the heads of the people” he means those of the highest repute, whose ignominy must have been most notable, because the eyes of all men are generally upon the great and noble. Hence, also, they deservedly incur the heavier punishment, because obscure persons do less harm by their example, nor are their acts so generally the objects of imitation. Let, therefore, those who are held in esteem beware lest they provoke others to sin by their evil deeds, for, in proportion to each man’s pre-eminence, the less excuse he deserves. Others interpret it differently, as if Moses were commanded to fetch the princes to give their sentence against the criminals; thus by the pronoun “them” they understood whosoever should be convictcd; but it is hardly probable that so great a multitude were hanged, and therefore I do not doubt but that reference is made to their peculiar punishment:.
