above
1 Peter 4:8
And above all things have fervent charity among yourselves: for charity shall cover the multitude of sins.
3 John 1:2
Beloved, I wish above all things that thou mayest prosper and be in health, even as thy soul prospereth.
swear not
Matthew 5:33-37
33
Again, ye have heard that it hath been said by them of old time, Thou shalt not forswear thyself, but shalt perform unto the Lord thine oaths:
34
But I say unto you, Swear not at all; neither by heaven; for it is God's throne:
35
Nor by the earth; for it is his footstool: neither by Jerusalem; for it is the city of the great King.
36
Neither shalt thou swear by thy head, because thou canst not make one hair white or black.
37
But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil.
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.
but
2 Corinthians 1:17-20
17
When I therefore was thus minded, did I use lightness? or the things that I purpose, do I purpose according to the flesh, that with me there should be yea yea, and nay nay?
18
But as God is true, our word toward you was not yea and nay.
19
For the Son of God, Jesus Christ, who was preached among you by us, even by me and Silvanus and Timotheus, was not yea and nay, but in him was yea.
20
For all the promises of God in him are yea, and in him Amen, unto the glory of God by us.
lest
James 3:1
My brethren, be not many masters, knowing that we shall receive the greater condemnation.
James 3:2
For in many things we offend all. If any man offend not in word, the same is a perfect man, and able also to bridle the whole body.
1 Corinthians 11:34
And if any man hunger, let him eat at home; that ye come not together unto condemnation. And the rest will I set in order when I come.
