Amos 1:6

¶Thus says the LORD, “For three transgressions of Gaza [in Philistia] and for four (multiplied delinquencies) I will not reverse its punishment or revoke My word concerning it, Because [as slave traders] they took captive the entire [Jewish] population [of defenseless Judean border villages, of which none was spared] And deported them to Edom [for the slave trade]. [Joel 3:6]
