4 Bible Verses about Not Swearing Oaths

but I say unto you, swear not at all; neither by heaven, for it is God's throne:

Above all things, my brethren, don't swear, neither by the heaven, nor by the earth, nor use any other oath; but let your affirmation, or negation, be sincere, lest you fall under condemnation.

but let your communication be, yes, yes; no, no: for whatever goes beyond this, is evil.

by him that said to him, "the Lord has swore, and will not repent, thou art a priest for ever after the order of Melchisedec."
