'Loyalty' in the Bible

Abram believed the Lord, and the Lord considered his response of faith as proof of genuine loyalty.

So when God had me wander from my father’s house, I said to her: Show your loyalty to me wherever we go and say about me: ‘He’s my brother.’”

Now swear to me right here in God's name that you will not deceive me, my children, or my descendants. Show me, and the land where you are staying, the same loyalty that I have shown you."
