Ezekiel 29:6 - Matthew Poole's English Annotations on the Holy Bible

This mighty overthrow shall be known through all Egypt, and as it shall fill them with fears and troubles, so it should be a convincing argument to them that God had done this, and punished them, and their proud king, who used to say, as Herodotus reports, that God could not turn him out of his kingdom. Because they, both king, princes, counsellors, and people of Egypt, have been a staff of reed; treacherously, as next verse, dealt with the Jews, whom they seduced to trust and depend on them, and then perfidiously broke promise with them. It was the sin of the Jews to trust Egypt; it was Egypt's great sin to falsify promise with the Jews, and for this God now punisheth Egypt.
