John Calvin on Amos 1:8

He therefore adds, that Jehovah Lord had spoken, saith the Lord Jehovah This was added for confirmation; for the Philistine were then in possession of many and strong defenses, so that they boldly laughed to scorn the threatening of the Prophet. He therefore brings forward here the name of God. Now follows the prediction respecting Tyrus: —

Amos 1:9-10

9. Thus saith the Lord; For three transgressions of Tyrus, and for four, I will not turn away the punishment thereof; because they delivered up the whole captivity to Edom, and remembered not the brotherly covenant:

9. Sic dicit Jehova, Super tribus sceleribus Tyri et super quatuor non ero ei propitius, quia concluserunt captivitatem perfectam in Edom, et non recordati sunt foederis fratrum:

10. But I will send a fire on the wall of Tyrus, which shall devour the palaces thereof.

10. Et mittam ignem in murum Tyri, qui comedet palatia ejus.
