Contradiction with Exodus 21:16
This verse states that anyone who kidnaps another person to sell them or keep them as a slave must be put to death, whereas Joel 3:8 implies a situation of selling captives.
Exodus 21:16: And he that stealeth a man, and selleth him, or if he be found in his hand, he shall surely be put to death.
Contradiction with Leviticus 25:39-42
These verses emphasize that an Israelite may not be sold as a slave and should be released in the Year of Jubilee, contrasting with the act of selling people as depicted in Joel 3:8.
Leviticus 25:39-42: And if thy brother [that dwelleth] by thee be waxen poor, and be sold unto thee; thou shalt not compel him to serve as a bondservant: [compel...: Heb. serve thyself with him with the service, etc]
Contradiction with Deuteronomy 24:7
This verse says a man who is caught kidnapping an Israelite to enslave them or sell them shall be put to death, in contrast to Joel 3:8 where taking captives for enslavement or sale is presented.
Deuteronomy 24:7: If a man be found stealing any of his brethren of the children of Israel, and maketh merchandise of him, or selleth him; then that thief shall die; and thou shalt put evil away from among you.
Contradiction with Galatians 3:28
This verse states that in Christ, there is neither slave nor free, contradicting the idea of selling people into slavery as seen in Joel 3:8.
Galatians 3:28: There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
Contradiction with Isaiah 58:6
Here, God urges the breaking of every yoke and letting the oppressed go free, which clashes with the depiction of selling individuals in Joel 3:8.
Isaiah 58:6: [Is] not this the fast that I have chosen? to loose the bands of wickedness, to undo the heavy burdens, and to let the oppressed go free, and that ye break every yoke? [the heavy...: Heb. the bundles of the yoke] [oppressed: Heb. broken]
Contradiction with Philemon 1:16
Paul speaks of not seeing a brother as a slave henceforth, contradicting the theme of selling people into slavery found in Joel 3:8.
Philemon 1:16: Not now as a servant, but above a servant, a brother beloved, specially to me, but how much more unto thee, both in the flesh, and in the Lord?
Paradox #1
The verse suggests a reversal of roles, where people previously oppressed or captured are now doing the same to others. This could be seen as a contradiction to teachings that emphasize forgiveness, compassion, and not repaying evil with evil, which are found in other parts of the Bible.
