Albert Barnes Commentary Ezekiel 29:13

"For thus saith the Lord Jehovah: At the end of forty years will I gather the Egyptians from the peoples whither they were scattered;" — Ezekiel 29:13 (ASV)

A similar respite was promised to Moab (Jeremiah 48:47), to Ammon (Jeremiah 49:6), and to Tyre (Isaiah 23:15).
