1 Timothy 1:8–10
8 Now we know that rthe law is good, if one uses it lawfully, 9 understanding this, that the slaw is not laid down for the just but for the lawless and disobedient, for the ungodly and sinners, for the unholy and profane, for those who strike their fathers and mothers, for murderers, 10 the sexually immoral, men who practice homosexuality, enslavers, liars, perjurers, and whatever else is contrary to sound3 doctrine
This says enslavers will be punished. Show me the verse that says you could enslave your enemies.
