Charles Spurgeon Commentary 2 Kings 13:3

"And the anger of Jehovah was kindled against Israel, and he delivered them into the hand of Hazael king of Syria, and into the hand of Benhadad the son of Hazael, continually." — 2 Kings 13:3 (ASV)

God's people cannot sin without coming under chastisement.

Remember this word of the Lord, "You only have I known of all the families of the earth: therefore I will punish you for all your iniquities." If you become church-members, and yet live unholy lives, you come under a special discipline, a discipline which I plainly see to be going on in the Church of God even to this day.

"For this cause," said Paul of the church in Corinth, "many are weak and sickly among you, and many sleep." No doubt God does send many rods to his rebellious family. He is not one of those fathers who "spare the rod, and spoil the child." Hazael and Benhadad were both wicked men; yet God used them as rods to chastise his sinning people.
