†23:13 Besieging a heavily fortified (walled) city was an ancient military tactic. The attackers would surround the city and cut off all supplies and communication to or from the inhabitants, then they would use siege towers to tear down the walls. The tower was a massive support structure for a heavy beam or log that was sharpened on one end and hung horizontally. It would be pushed against a wall and worked in such a way as to dislodge the stones that had been stacked to form the wall.
‡23:18 Tyre was destroyed by Nebuchadnezzar in 572 ʙ.c. and lay desolate for seventy years. The new city built on the island was taken by Alexander the Great in 332 ʙ.c. Eventually Christianity prevailed at Tyre. Jesus visited there (Matt 15:21) and so did Paul (Acts 21:3-6). In his commentary on Isaiah Eusebius says that when the church of God was founded in Tyre, much of its wealth was consecrated to God and presented for the support of ministers. This is also the testimony of Jerome, the Latin church father writing in the fourth century.
