'Falsely' in the Bible

Then he said to me, “This is the curse that is going out over the face of the whole land; for everyone who steals will be cut off according to the writing on one side, and everyone who swears [oaths falsely] shall be cut off according to the writing on the other side.

I will send the curse out,” declares the Lord of hosts, “and it will enter the house of the thief and the house of the one who swears falsely by My name; and it will spend the night in that house and consume it, both its timber and its stones.”

And if anyone still [appears as a prophet and falsely] prophesies, then his father and his mother who gave birth to him will say to him, ‘You shall not live, for you have spoken lies in the name of the Lord’; and his father and his mother who gave birth to him shall pierce him through when he prophesies.
