2 Bible Verses about Swearing Being Forbidden

But I say to you, do not take any oath, [saying] 'by heaven,' for it is God's throne;

But above everything else, my brothers, do not take oaths, not "by the heaven," nor "by the earth," nor by any other oath. But your "yes" should be [simply] "yes," and your "no," [simply] "no," so you do not fall under condemnation.
