AKJV(i)
17 And he said to David, You are more righteous than I: for you have rewarded me good, whereas I have rewarded you evil.
18 And you have showed this day how that you have dealt well with me: for as much as when the LORD had delivered me into your hand, you killed me not.
19 For if a man find his enemy, will he let him go well away? why the LORD reward you good for that you have done to me this day.
