'Loyal' in the Bible

Saul said to the Kenites, "Go, leave! Withdraw from among the Amalekites so that I do not destroy you with them. You have shown loyal love to all the {Israelites} when they came up from Egypt." So the Kenites left from among [the] Amalekites.

So you must show loyal love to your servant, for you have brought your servant into a covenant of Yahweh with you. But if there [is] guilt in me, [then] kill me yourself! But why should you bring me to your father?"

And not while I am still alive, will you not show the loyal love of Yahweh with me, that I may not die?

And do not cut off your loyal love from {my family} forever, not [even] when Yahweh {exterminates} each of the enemies of David from the face of the earth."
