Matthew 5:34
But I say unto you, Swear not at all; neither by heaven; for it is God's seat:
Isaiah 66:1
Thus sayeth the LORD: Heaven is my seat, and the earth is my footstool. Where shall now the house stand, that ye build unto me? And where shall be the place, that I will dwell in?
James 5:12
But above all things, my brethren, swear not: neither by heaven, neither by earth, neither by any other oath. Let your yea be "yea," and your nay, "nay," lest ye fall into hypocrisy.
Deuteronomy 23:21-23
When thou hast vowed a vow unto the LORD thy God, see thou be not slack to pay it. For he will surely require it of thee, and it shall be sin unto thee.
Ecclesiastes 9:2
It happeneth unto one as unto another; It goeth with the righteous as with the ungodly; with the good and clean as with the unclean; with him that offereth as with him that offereth not; like as it goeth with the virtuous, so goeth it also with the sinner; As it happeneth unto the perjured, so happeneth it also unto him that is afraid to be foresworn.
Isaiah 57:15
For thus sayeth the high and excellent, even he that dwelleth in everlastingness, whose name is the holy one: I dwell high above and in the sanctuary, and with him also, that is of a contrite and humble spirit: that I may heal a troubled mind, and a contrite heart.
Matthew 23:16-22
Woe be unto you, blind guides, for ye which say, 'Whosoever swear by the temple, it is nothing: but whosoever swear by the gold of the temple, he offendeth.'
