'Swear' 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,

The men said to her, "We [will be] released from this oath of yours that you made us swear.

But if you report this business of ours, we will be released from your oath that you made us swear."

so as not to go among these remaining nations with you; {do not profess} the name of their gods, and do not swear by them, serve them, or {bow down to them}.
