“Certaine men, the children of Belial, are gone out from among you, and haue withdrawen the inhabitants of their citie, saying, Let vs goe & serue other gods, which ye haue not knowen:”
1611 King James Version (KJV)
13:13 Children of Belial - It signifies properly persons without yoke, vile and wretched miscreants, lawless and rebellious, that will suffer no restraint, that neither fear God, nor reverence man. From among you - That is, from your church and religion. It notes a separation from them, not in place (as appears by their partnership with their fellow citizens both in the sin and punishment) but in heart, doctrine and worship.
