Complete Commentary on the Whole Bible, by Matthew Henry, at sacred-texts.com
(Ch2 11:1-12) Rehoboam forbidden to war against Israel.
(Ch2 11:13-23) The priests and Levites find refuge in Judah.
2 Chronicles 11:1
A few good words might have prevented the rebellion of Rehoboam's subjects; but all the force of his kingdom cannot bring them back. And it is in vain to contend with the purpose of God, when it is made known to us. Even those who are destitute of true faith, will at times pay some regard to the word of God, and be kept by it from wrong actions, to which they are prone by nature.
2 Chronicles 11:13
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.
