Contradiction with Ecclesiastes 5:4
This verse states it is better not to vow than to vow and not pay, which supports Deuteronomy 23:22 in encouraging caution with vows, rather than contradicting it.
Ecclesiastes 5:4: When thou vowest a vow unto God, defer not to pay it; for [he hath] no pleasure in fools: pay that which thou hast vowed.
Contradiction with Numbers 30:2
This verse emphasizes that a person must fulfill vows, similar to Deuteronomy 23:22, rather than contradicting it.
Numbers 30:2: If a man vow a vow unto the LORD, or swear an oath to bind his soul with a bond; he shall not break his word, he shall do according to all that proceedeth out of his mouth. [break: Heb. profane]
Contradiction with Matthew 5:34-37
Jesus teaches not to swear oaths at all, which contrasts with the idea of making vows but not failing to perform them mentioned in Deuteronomy 23:22.
Matthew 5:34-37: But I say unto you, Swear not at all; neither by heaven; for it is God's throne:
Contradiction with James 5:12
Advises not to swear by anything, which contrasts the focus on not refraining from vowing in Deuteronomy 23:22.
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.
Paradox #1
The contradiction could arise from the idea that one is not obligated to make a vow, but once made, it must be fulfilled. This could conflict with beliefs about unconditional promises or obligations, suggesting that one shouldn't make promises they can't keep, yet offering the option to not vow at all might seem inconsistent with the importance of commitment.
