No foot of man shall pass through it, nor foot of beast shall pass through it, neither shall it be inhabited forty years.

Wesley's Notes

29:11 Forty years - These forty years began about the thirtieth year of Jeconiah's captivity, and end with the seventieth year of the captivity, which was the first of Cyrus.

Jamieson-Fausset-Brown Bible Commentary

11. forty years-answering to the forty years in which the Israelites, their former bondsmen, wandered in "the wilderness" (compare Note, see on [1072]Eze 29:5). Jerome remarks the number forty is one often connected with affliction and judgment. The rains of the flood in forty days brought destruction on the world. Moses, Elias, and the Saviour fasted forty days. The interval between Egypt's overthrow by Nebuchadnezzar and the deliverance by Cyrus, was about forty years. The ideal forty years' wilderness state of social and political degradation, rather than a literal non-passing of man or beast for that term, is mainly intended (so Eze 4:6; Isa 19:2, 11).

Matthew Henry's Concise Commentary

29:1-16 Worldly, carnal minds pride themselves in their property, forgetting that whatever we have, we received it from God, and should use it for God. Why, then, do we boast? Self is the great idol which all the world worships, in contempt of God and his sovereignty. God can force men out of that in which they are most secure and easy. Such a one, and all that cleave to him, shall perish together. Thus end men's pride, presumption, and carnal security. The Lord is against those who do harm to his people, and still more against those who lead them into sin. Egypt shall be a kingdom again, but it shall be the basest of the kingdoms; it shall have little wealth and power. History shows the complete fulfilment of this prophecy. God, not only in justice, but in wisdom and goodness to us, breaks the creature-stays on which we lean, that they may be no more our confidence.
