12 Above all, my brothers, do not swear--not by heaven or by earth or by anything else. Let your "Yes" be yes, and your "No," no, or you will be condemned.
4 When you make a vow to God, do not delay in fulfilling it. He has no pleasure in fools; fulfill your vow. 5 It is better not to vow than to make a vow and not fulfill it.
33 "Again, you have heard that it was said to the people long ago, 'Do not break your oath, but keep the oaths you have made to the Lord.' 34 But I tell you, Do not swear at all: either by heaven, for it is God's throne; 35 or by the earth, for it is his footstool; or by Jerusalem, for it is the city of the Great King. 36 And do not swear by your head, for you cannot make even one hair white or black. 37 Simply let your 'Yes' be 'Yes,' and your 'No,No'; anything beyond this comes from the evil one.
1 LORD, who may dwell in your sanctuary? Who may live on your holy hill? 2 He whose walk is blameless and who does what is righteous, who speaks the truth from his heart 3 and has no slander on his tongue, who does his neighbor no wrong and casts no slur on his fellowman, 4 who despises a vile man but honors those who fear the LORD, who keeps his oath even when it hurts, 5 who lends his money without usury and does not accept a bribe against the innocent. He who does these things will never be shaken.
19 God is not a man, that he should lie, nor a son of man, that he should change his mind. Does he speak and then not act? Does he promise and not fulfill?
9 The Lord is not slow in keeping his promise, as some understand slowness. He is patient with you, not wanting anyone to perish, but everyone to come to repentance.
14 if my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land.
