'Loyalty' in the Bible

So then please swear to me by Yahweh, because {I have shown loyalty to you}, and {you will also show loyalty} {to my family}. You must give me a sign of good faith,

And the men said to her, "{Our lives for yours}. If you do not report this business of ours, {we will show you loyalty and faithfulness} when Yahweh gives us the land."

Now obey the Lord and worship him with integrity and loyalty. Put aside the gods your ancestors worshiped beyond the Euphrates and in Egypt and worship the Lord.
