John Gill Commentary Ezekiel 16:26

"Thou hast also committed fornication with the Egyptians, thy neighbors, great of flesh; and hast multiplied thy whoredom, to provoke me to anger." — Ezekiel 16:26 (ASV)

You have also committed fornication with the Egyptians. By entering into leagues and alliances with them, and seeking to them for help and assistance against their enemies; from whose bondage they had formerly been delivered, and whose society they were cautioned against; and yet they forsook the Lord, and joined themselves to them by solemn covenant;

And not only so, but fell into the worship of their idols, who were a people of all others the most superstitious, and given to idolatry; and many of their idolatrous rites and ceremonies were received and retained by the Jews, as the worshipping of Tammuz, and other idols:

your neighbours, great of flesh: Being their neighbours, and full of power and strength to assist them, they courted their friendship and alliance; and their idolatries being many and monstrous, were the more courted by them:

The allusion is to women of shameless impudence and insatiable lust, who covet men, whose flesh is as the flesh of asses, and their issue as horses, (Ezekiel 23:20); flesh here signifies the privy parts of men; so Ben Melech;

and have increased your whoredoms, to provoke my anger: Multiplied their idolatries, which they learned of the Egyptians, a people much given thereunto; and which were abominable and highly provoking to God, (1 Peter 4:3).

The Targum is, "you have increased your idols."
