21. I cast the dust thereof into the brook that descended out of the mount—that is, "the smitten rock" (El Leja) which was probably contiguous to, or a part of, Sinai. It is too seldom borne in mind that though the Israelites were supplied with water from this rock when they were stationed at Rephidim (Wady Feiran), there is nothing in the Scripture narrative which should lead us to suppose that the rock was in the immediate neighborhood of that place (see on Ex 17:5). The water on this smitten rock was probably the brook that descended from the mount. The water may have flowed at the distance of many miles from the rock, as the winter torrents do now through the wadies of Arabia-Petræa (Ps 78:15, 16). And the rock may have been smitten at such a height, and at a spot bearing such a relation to the Sinaitic valleys, as to furnish in this way supplies of water to the Israelites during the journey from Horeb by the way of mount Seir and Kadesh-barnea (De 1:1, 2). On this supposition new light is, perhaps, cast on the figurative language of the apostle, when he speaks of "the rock following" the Israelites (1Co 10:4) [WILSON, Land of the Bible].

     26-32. Jeroboam said in his heart, Now shall the kingdom return to the house of David—Having received the kingdom from God, he should have relied on the divine protection. But he did not. With a view to withdraw the people from the temple and destroy the sacred associations connected with Jerusalem, he made serious and unwarranted innovations on the religious observances of the country, on pretext of saving the people the trouble and expense of a distant journey. First, he erected two golden calves—the young bulls, Apis and Mnevis, as symbols (in the Egyptian fashion) of the true God, and the nearest, according to his fancy, to the figures of the cherubim. The one was placed at Dan, in the northern part of his kingdom; the other at Beth-el, the southern extremity, in sight of Jerusalem, and in which place he probably thought God was as likely to manifest Himself as at Jerusalem (Ge 32:1-32; 2Ki 2:2). The latter place was the most frequented—for the words (1Ki 12:30) should be rendered, "the people even to Dan went to worship before the one" (Jer 48:13; Am 4:4, 5; 5:5; Ho 5:8; 10:8). The innovation was a sin because it was setting up the worship of God by symbols and images and departing from the place where He had chosen to put His name. Secondly, he changed the feast of tabernacles from the fifteenth of the seventh to the fifteenth of the eighth month. The ostensible reason might be, that the ingathering or harvest was later in the northern parts of the kingdom; but the real reason was to eradicate the old association with this, the most welcome and joyous festival of the year.
