'Loyal' in the Bible

but now your reign will not endure. The Lord has found a man loyal to Him, and the Lord has appointed him as ruler over His people, because you have not done what the Lord commanded.”

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.

You must be loyal to your servant, for you have made a covenant with your servant in the Lord's name. If I am guilty, you yourself kill me! Why bother taking 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."
