‏ 2 Kings 6:21-23

Verse 21

My father, shall I smite - This was dastardly; the utmost he could have done with these men, when thus brought into his hand, was to make them prisoners of war.
Verse 22

Whom thou hast taken captive - Those who in open battle either lay down their arms, or are surrounded, and have their retreat cut off, are entitled to their lives, much more those who are thus providentially put into thy hand, without having been in actual hostility against thee. Give them meat and drink, and send them home to their master, and let them thus know that thou fearest him not, and art incapable of doing an ungenerous or unmanly action.
Verse 23

He prepared great provision for them - These, on the return to their master, could tell him strange things about the power of the God of Israel, and the magnanimity of its king.

So the bands of Syria came no more - Marauding parties were no more permitted by the Syrian king to make inroads upon Israel. And it is very likely that for some considerable time after this, there was no war between these two nations. What is mentioned in the next verse was more than a year afterwards.
