'Please' 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,

Please, my Lord! What can I say after {Israel has fled from its enemies}?

And Joshua said to Achan, "My son, please, give glory to Yahweh the God of Israel, and give him a doxology in court. Tell me, please, what you have done; do not hide [it] from me."
