And all the inhabitants of Egypt shall know that I am the LORD, because they have been a staff of reed to the house of Israel. They have been a staff of reed - An inefficient and faithless ally. The Israelites expected assistance from them when Nebuchadnezzar came against Jerusalem; and they made a feint to help them, but retired when Nebuchadnezzar went against them. Thus were the Jews deceived and ultimately ruined, see Ezekiel 29:7.
