The third instance is the revolt headed by Korah, Dathan, and Abiram against the exclusive Aaronic priesthood (vv. 16-18). It was rebellion against God, for He had set apart Aaron as His own, and therefore the unusual title of "the holy one of Jehovah" is here given to the high priest. The expression recalls the fierce protest of the mutineers, addressed to Moses and Aaron, "Ye take too much upon you, seeing all the congregation are holy" (Num. xvi. 3); and also Moses' answer, "Jehovah will show ... who is holy." Envy often masquerades as the champion of the rights of the community, when it only wishes to grasp these for itself. These aristocratic democrats cared nothing for the prerogatives of the nation, though they talked about them. They wanted to pull down Aaron, not to lift up Israel. Their end is described with stern brevity, in language coloured by the narrative in Numbers, from which the phrases "opened" (_i.e._, her mouth) and "covered" are drawn. Korah is not mentioned here, in which the psalm follows Num. xvi. and Deut. xi. 6, whereas Num. xxvi. 10 includes Korah in the destruction. The difficulty does not seem to have received any satisfactory solution. But Cheyne is too peremptory when he undertakes to divine the reason for the omission of Korah here and in Deut. xi. 6, "because he was a Levite and his name was dear to temple-poets." Such clairvoyance as to motives is beyond ordinary vision. In ver. 18 the fate of the two hundred and fifty "princes of Israel" who took part in the revolt is recorded as in Num. xvi. 35.
The worship of the calf is the fourth instance (vv. 19-23) in the narrative of which the psalmist follows Exod. xxxii., but seems also to have Deut. ix. 8-12 floating in his mind, as appears from the use of the name "Horeb," which is rare in Exodus and frequent in Deuteronomy. Ver. 20 is apparently modelled on Jer. ii. 11: "My people have changed their glory for that which doth not profit." Compare also Paul's "_changed_ the _glory_ of the incorruptible God for the _likeness_," etc. (Rom. i. 23). "His glory" is read instead "their glory" by Noldeke, Graetz, and Cheyne, following an old Jewish authority. The LXX., in Codd. Alex. and Sin. (second hand), has this reading, and Paul seems to follow it in the passage just quoted. It yields a worthy meaning, but the existing text is quite appropriate. It scarcely means that God was the source of Israel's glory or their boast, for the word is not found in that sense. It is much rather the name for the collective attributes of the revealed Godhead, and is here substantially equivalent to "their God," that lustrous Light which, in a special manner, belonged to the people of revelation, on whom its first and brightest beams shone. The strange perverseness which turned away from such a radiance of glory to bow down before an idol is strikingly set forth by the figure of bartering it for an image, and that of an ox that ate grass. The one true Substance given away for a shadow! The lofty Being whose light filled space surrendered: and for what? A brute that had to feed, and that on herbage! Men usually make a profit, or think they do, on their barter: but what do they gain by exchanging God for anything? Yet _we_ keep making the same mistake of parting with Substance for shadows. And the reason which moved Israel is still operative. As before, the psalmist traces their mad apostasy to forgetfulness of God's deeds. The list of these is now increased by the addition of those at the Red Sea. With every step new links were added to the chain that should have bound the recipients of so many mercies to God. Therefore each new act of departure was of a darker hue of guilt, and drew on the apostates severer punishment, which also, rightly understood, was greater mercy.
