Amos 1:6 AMPC

[6] Thus says the Lord: For three transgressions of Gaza [a city in Philistia] and for four [for multiplied delinquencies], I will not reverse the punishment of it or revoke My word concerning it, because [as slave traders] they carried away captive the whole [Jewish] population [of defenseless Judean border villages, of which none was spared, none left behind] and delivered them up to Edom [for the slave trade].
