'Take an Oath' in the Bible

And Moses took the bones of Joseph with him, for Joseph had made the children of Israel take an oath, saying, God will certainly keep you in mind; and you are to take my bones away with you.

If they do not get the thief, let the master of the house come before the judges and take an oath that he has not put his hand on his neighbour's goods.

the two of them are to take an oath in the LORD's presence that the accused has not taken his neighbor's property. Its owner is to accept this, and the neighbor is not to make restitution.
