TSK · Deuteronomy 5:11

"You shall not take the name of Yahweh your God in vain, for Yahweh will not hold him guiltless who takes his name in vain.

You shall fear Yahweh your God; and you shall serve him, and shall swear by his name.

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."

But above all things, my brothers, don't swear, neither by heaven, nor by the earth, nor by any other oath; but let your "yes" be "yes," and your "no," "no;" so that you don't fall into hypocrisy.
