Swear
Deuteronomy 23:21-23
21
"When you make a vow to the LORD your God, you shall not be slack to pay it; for the LORD your God will surely require it of you, and it would be sin in you.
22
But if you refrain from vowing, it shall be no sin in you.
23
You shall be careful to perform what has passed your lips, for you have voluntarily vowed to the LORD your God what you have promised with your mouth.
Ecclesiastes 9:2
since one fate comes to all, to the righteous and the wicked, to the good and the evil, to the clean and the unclean, to him who sacrifices and him who does not sacrifice. As is the good man, so is the sinner; and he who swears is as he who shuns an oath.
James 5:12
But above all, my brethren, do not swear, either by heaven or by earth or with any other oath, but let your yes be yes and your no be no, that you may not fall under condemnation.

Matthew 23:16-22
16
You blind fools! For which is greater, the gold or the temple that has made the gold sacred?
17
And you say, `If any one swears by the altar, it is nothing; but if any one swears by the gift that is on the altar, he is bound by his oath.'
18
You blind men! For which is greater, the gift or the altar that makes the gift sacred?
19
So he who swears by the altar, swears by it and by everything on it;
20
and he who swears by the temple, swears by it and by him who dwells in it;
21
and he who swears by heaven, swears by the throne of God and by him who sits upon it.
22
"Woe to you, scribes and Pharisees, hypocrites! for you tithe mint and dill and cummin, and have neglected the weightier matters of the law, justice and mercy and faith; these you ought to have done, without neglecting the others.
Isaiah 57:15

Isaiah 66:1
Thus says the LORD: "Heaven is my throne and the earth is my footstool; what is the house which you would build for me, and what is the place of my rest?
