'Kindness' in the Bible

Saul said to the Kenites, “Go, leave, go down from the Amalekites, so that I do not destroy you along with them; for you showed kindness to all the Israelites when they went up from Egypt.” So the Kenites departed from among the Amalekites.

You shall never cut off your lovingkindness and faithfulness from my house, not even when the Lord cuts off every one of the enemies of David from the face of the earth.”
