'Show Kindness' in the Bible

And David said, “Is there still anyone left of the house (family) of Saul to whom I may show kindness for Jonathan’s sake?”

Then David said, “I will show kindness to Hanun the son of Nahash, just as his father did to me.” So David sent [a letter along with] some of his servants to console him in regard to his father’s death; and David’s servants came into the land of the Ammonites.
