'Show' 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."
