Swear
Deuteronomy 23:21-23
21
When thou shalt vow a vow unto the LORD thy God, thou shalt not slack to pay it: for the LORD thy God will surely require it of thee; and it would be sin in thee.
22
But if thou shalt forbear to vow, it shall be no sin in thee.
23
That which is gone out of thy lips thou shalt keep and perform; even a freewill offering, according as thou hast vowed unto the LORD thy God, which thou hast promised with thy mouth.
Ecclesiastes 9:2
All things come alike to all: there is one event to the righteous, and to the wicked; to the good and to the clean, and to the unclean; to him that sacrificeth, and to him that sacrificeth not: as is the good, so is the sinner; and he that sweareth, as he that feareth an oath.
James 5:12
But above all things, my brethren, swear not, neither by heaven, neither by the earth, neither by any other oath: but let your yea be yea; and your nay, nay; lest ye fall into condemnation.

Matthew 23:16-22
16
Woe unto you, ye blind guides, which say, Whosoever shall swear by the temple, it is nothing; but whosoever shall swear by the gold of the temple, he is a debtor!
17
Ye fools and blind: for whether is greater, the gold, or the temple that sanctifieth the gold?
18
And, Whosoever shall swear by the altar, it is nothing; but whosoever sweareth by the gift that is upon it, he is guilty.
19
Ye fools and blind: for whether is greater, the gift, or the altar that sanctifieth the gift?
20
Whoso therefore shall swear by the altar, sweareth by it, and by all things thereon.
21
And whoso shall swear by the temple, sweareth by it, and by him that dwelleth therein.
22
And he that shall swear by heaven, sweareth by the throne of God, and by him that sitteth thereon.
Isaiah 57:15
For thus saith the high and lofty One that inhabiteth eternity, whose name is Holy; I dwell in the high and holy place, with him also that is of a contrite and humble spirit, to revive the spirit of the humble, and to revive the heart of the contrite ones.
Isaiah 66:1
Thus saith the LORD, The heaven is my throne, and the earth is my footstool: where is the house that ye build unto me? and where is the place of my rest?
