'Swear' in the Bible

and you shall swear, 'As Yahweh lives,' in truth, in justice, and in righteousness. The nations shall bless themselves in him, and in him shall they glory."

Though they say, 'As Yahweh lives;' surely they swear falsely."

Will you steal, murder, and commit adultery, and swear falsely, and burn incense to Baal, and walk after other gods that you have not known,

It shall happen, if they will diligently learn the ways of my people, to swear by my name, As Yahweh lives; even as they taught my people to swear by Baal; then shall they be built up in the midst of my people.

But if you will not hear these words, I swear by myself, says Yahweh, that this house shall become a desolation.
