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: Tyrus - See an ample description of this place, and of its desolation and final ruin, in the notes on Ezekiel 26 (note).
The brotherly covenant - This possibly refers to the very friendly league made between Solomon and Hiram, king of Tyre, 1 Kings 5:12; but some contend that the brotherly covenant refers to the consanguinity between the Jews and Edomites. The Tyrians, in exercising cruelties upon these, did it, in effect, on the Jews, with whom they were connected by the most intimate ties of kindred; the two people having descended from the two brothers, Jacob and Esau.
