Though I have bound [and] strengthened their arms,.... As a surgeon sets a broken arm and swathes and binds it, and so restores it to its former strength, or at least to a good degree of strength again, so the Lord dealt with Israel; their arms were broken, and their strength weakened, and they greatly distressed and reduced by the Syrians in the times of Jehoahaz; but they were brought into a better state and condition in the times of Joash and Jeroboam the second; the former retook several cities out of the hands of the Syrians, and the latter restored the border of Israel, and greatly enlarged it; and as all this was done through the blessing of divine Providence, the Lord is said to do it himself.
Some render it, "though I have chastised, I have strengthened their arms" ; though he corrected them for their sins in the times of Jehoahaz, and suffered their arms to be broken by their enemies, for their instruction, and in order to bring them to repentance for their sins; yet he strengthened them again in the following reigns:yet do they imagine mischief against me; so ungrateful were they, they contrived to do hurt to his prophets that were sent to them in his name, to warn them of their sins and danger, and exhort them to repent, and forsake their idolatrous worship, and other sins; and they sought by all means to dishonour the name of the Lord, by imputing their success in the reigns of Joash and Jeroboam to their idols, and not unto him; and so hardened themselves against him, and in their evil ways.
