5 And the king gave this command to Joab, Abishai, and Ittai: "For my sake, deal gently with young Absalom." And all the troops heard the king give this order to his commanders.

Commentary on 2 Samuel 18:1-8

(Read 2 Samuel 18:1-8)

How does David render good for evil! Absalom would have only David smitten; David would have only Absalom spared. This seems to be a resemblance of man's wickedness towards God, and God's mercy to man, of which it is hard to say which is most amazing. Now the Israelites see what it is to take counsel against the Lord and his anointed.
