Amos 1:6-12 AMP

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]. [Joel 3:6.]

7 So I will send a fire on the wall of Gaza which shall devour its strongholds.

8 And I will cut off the inhabitants from Ashdod and him who holds the scepter from Ashkelon, and I will turn My hand against Ekron; and the rest of the Philistines [in Gath and the towns dependent on these four Philistine cities] shall perish, says the Lord God. [Josh. 13:3.]

9 Thus says the Lord: For three transgressions of Tyre and for four [for multiplied delinquencies], I will not reverse the punishment of it or revoke My word concerning it, because they [as middlemen] delivered up a whole [Jewish] population to Edom and did not [seriously] remember their brotherly covenant. [I Kings 5:1, 12; 9:12, 13.]

10 So I will send a fire on the wall of Tyre which shall devour its strongholds.

11 Thus says the Lord: For three transgressions of Edom [descendants of Esau] and for four [for multiplied delinquencies], I will not reverse the punishment of it or revoke My word concerning it, because he pursued his brother Jacob (Israel) with the sword, corrupting his compassions and casting off all pity, and his anger tore perpetually and his wrath he kept and heeded forever.

12 So I will send a fire upon Teman which shall devour the strongholds of Bozrah [in Edom].
