Albert Barnes Commentary Ezekiel 29:16

"And it shall be no more the confidence of the house of Israel, bringing iniquity to remembrance, when they turn to look after them: and they shall know that I am the Lord Jehovah." — Ezekiel 29:16 (ASV)

The false confidence of the Israelites brought to remembrance, that is, discovered in the sight of God and man, their iniquity, that is, their treachery and perjury to the Chaldeans. Their falsehood was made evident when they looked after (turned to) the Egyptians and sought their aid in rebellion. The ruin of Egypt shall put an end to all this.
