'Swear' in the Bible
Now therefore, please swear to me by the Lord, since I have dealt kindly with you, that you also will deal kindly with my father’s household, and give me a pledge of truth,
The men said to her, “We shall be free from this oath to you which you have made us swear,
But if you tell this business of ours, then we shall be free from the oath which you have made us swear.”
so that you will not associate with these nations, these which remain among you, or mention the name of their gods, or make anyone swear by them, or serve them, or bow down to them.
