'Kindness of God' in the Bible

And the king said, Is there not yet any of the house of Saul, that I may shew the kindness of God to him? And Ziba said to the king, Jonathan has yet a son, who is lame on his feet.

{To the chief Musician: an instruction. Of David; when Doeg the Edomite came and told Saul, and said unto him, David came to the house of Ahimelech.} Why boastest thou thyself in evil, thou mighty man? The loving-kindness of God abideth continually.

But as for me, I am like a green olive-tree in the house of God: I will confide in the loving-kindness of God for ever and ever.
