Albert Barnes Commentary Ezekiel 27:3

"and say unto Tyre, O thou that dwellest at the entry of the sea, that art the merchant of the peoples unto many isles, thus saith the Lord Jehovah: Thou, O Tyre, hast said, I am perfect in beauty." — Ezekiel 27:3 (ASV)

Entry - literally, “entries.” Ancient Tyre had two ports, that called the Sidonian to the north, the Egyptian to the south; the former exists to the present day. The term “entry of the sea” is naturally enough applied to a harbor as a place from which ships enter and return from the sea. The city was known in the earliest times as “Tyre the port.”
