31 And he made places for worship at the high places, and made priests, who were not Levites, from among all the people. 32 And Jeroboam gave orders for a feast in the eighth month, on the fifteenth day of the month, like the feast which is kept in Judah, and he went up to the altar. And in the same way, in Beth-el, he gave offerings to the oxen which he had made, placing in Beth-el the priests of the high places he had made. 33 He went up to the altar he had made in Beth-el on the fifteenth day of the eighth month, the month fixed by him at his pleasure; and he gave orders for a feast for the people of Israel, and went up to the altar, and there he made the smoke of his offerings go up.

Commentary on 1 Kings 12:25-33

(Read 1 Kings 12:25-33)

Jeroboam distrusted the providence of God; he would contrive ways and means, and sinful ones too, for his own safety. A practical disbelief of God's all-sufficiency is at the bottom of all our departures from him. Though it is probable he meant his worship for Jehovah the God of Israel, it was contrary to the Divine law, and dishonourable to the Divine majesty to be thus represented. The people might be less shocked at worshipping the God of Israel under an image, than if they had at once been asked to worship Baal; but it made way for that idolatry. Blessed Lord, give us grace to reverence thy temple, thine ordinances, thine house of prayer, thy sabbaths, and never more, like Jeroboam, to set up in our hearts any idol of abomination. Be thou to us every thing precious; do thou reign and rule in our hearts, the hope of glory.
