The eleventh year - This was the year in which Jerusalem was taken; the eleventh of the captivity of Jeconiah, and the eleventh of the reign of Zedekiah. What month we are not told, though the day is mentioned. There have been many conjectures about this, which are not of sufficient consequence to be detailed.
Prophecies against Tyre. The siege of Tyre lasted thirteen years beginning 585 b.c., about three years after the capture of Jerusalem. While besieging Jerusalem, Nebuchadnezzar had driven Pharaoh Hophra back to the borders of Egypt. Tyre being thus relieved from a dangerous enemy, was exulting in her own deliverance, and in her neighbor‘s ruin, when Ezekiel predicted the calamity about to befall her. The name Tyre means rock, and was given to the city in consequence of its position. This island-rock was the heart of Tyre, and the town upon the continent - called “Old Tyre,” possibly as having been the temporary position of the first settlers - was the outgrowth of the island city. The scanty records of ancient history give no, distinct evidence of the capture of insular Tyre by Nebuchadnezzar; but the fact is very probable. Compare especially Ezekiel 26:7-12; Ezekiel 29:18. The present state of Tyre is one of utter desolation, though the end was long delayed (compare Isaiah 23). Tyre was great and wealthy under Persian, Greek, Roman, and even Muslim masters. The final ruin of Tyre was due to the sultan of Egypt (1291 a.d.).
In the first day of the month - The number of the month being omitted, many suppose “the month” to mean the month when Jerusalem was taken (the rebirth month), called “the month,” as being so well known. The capture of the city is known to have taken place on “the ninth day of the fourth month” and its destruction on “the seventh day of the fifth month.” This prophecy therefore preceded by a few days the capture of the city. The condition of Jerusalem in the latter months of its siege was such that the Tyrians may well have exulted as though it had already fallen.
