'Kindness' in the Bible

So David sent messengers to the people of Jabesh Gilead and told them, "May you be blessed by the Lord because you have shown this kindness to your lord Saul by burying him.

Now may the Lord show you true kindness! I also will reward you, because you have done this deed.

Then David asked, "Is anyone still left from the family of Saul, so that I may extend kindness to him for the sake of Jonathan?"

The king asked, "Is there not someone left from Saul's family, that I may extend God's kindness to him?" Ziba said to the king, "One of Jonathan's sons is left; both of his feet are crippled."

David said to him, "Don't be afraid, because I will certainly extend kindness to you for the sake of Jonathan your father. You will be a regular guest at my table."
