Separate yourselves, from among this congregation,.... Not only from Korah's company, but from the congregation of the children of Israel, whom Korah had got together, besides the two hundred fifty men that were at first with him; who by their words and behaviour, and particularly by their association and standing along with him, showed them to be on his side, which greatly provoked the Lord:

that I may consume them in a moment; by fire from him, as the two hundred fifty men were afterwards consumed, Numbers 16:35.

Separate yourselves from among this congregation, that I may consume them in a moment.

16:16-22 The same glory of the Lord that appeared to place Aaron in his office at first, Le 9:23, now appeared to confirm him in it; and to confound those who set up against him. Nothing is more terrible to those who are conscious of guilt, than the appearance of the Divine glory. See how dangerous it is to have fellowship with sinners, and to partake with them. Though the people had treacherously deserted them, yet Moses and Aaron approved themselves faithful shepherds of Israel. If others fail in their duty to us, that does not take away the obligations we are under to seek their welfare. Their prayer was a pleading prayer, and it proved a prevailing one.
