11:13-23 When the priests and Levites came to Jerusalem, the devout, pious Israelites followed them. Such as set their hearts to seek the Lord God of Israel, left the inheritance of their fathers, and went to Jerusalem, that they might have free access to the altar of God, and be out of the temptation to worship the calves. That is best for us, which is best for our souls; in all our choices, religious advantages must be sought before all outward conveniences. Where God's faithful priests are, his faithful people should be. And when it has been proved that we are willing to renounce our worldly interests, so far as we are called to do so for the sake of Christ and his gospel, we have good evidence that we are truly his disciples. And it is the interest of a nation to protect religion and religious people.

13-17. the priests and the Levites … resorted to him out of all their coasts—This was an accession of moral power, for the maintenance of the true religion is the best support and safeguard of any nation; and as it was peculiarly the grand source of the strength and prosperity of the Hebrew monarchy, the great numbers of good and pious people who sought an asylum within the territories of Judah contributed greatly to consolidate the throne of Rehoboam. The cause of so extensive an emigration from the kingdom of Israel was the deep and daring policy of Jeroboam, who set himself to break the national unity by entirely abolishing, within his dominions, the religious institutions of Judaism. He dreaded an eventual reunion of the tribes if the people continued to repair thrice a year to worship in Jerusalem as they were obliged by law to do. Accordingly, on pretense that the distance of that city was too great for multitudes of his subjects, he fixed upon two more convenient places, where he established a new mode of worshipping God under gross and prohibited symbols [1Ki 12:26-33]. The priests and Levites, refusing to take part in the idolatrous ceremonies, were ejected from their living [2Ch 11:13, 14]. Along with them a large body of the people who faithfully adhered to the instituted worship of God, offended and shocked by the impious innovations, departed from the kingdom.
