Charles Spurgeon Commentary Ezekiel 16:3

"and say, Thus saith the Lord Jehovah unto Jerusalem: Thy birth and thy nativity is of the land of the Canaanite; the Amorite was thy father, and thy mother was a Hittite." — Ezekiel 16:3 (ASV)

Abraham, the father of the nation, came from beyond the flood; but here, because of the sin of the people, God attributes their birth to the place of their settlement rather than to that chosen and noble man.

They had lived so long in Canaan that they had grown to be Canaanites. Their habits were so evil that there was little choice between the Israelites and the Amorites and Hittites whom God had struck in his wrath.

So the Lord says: "Your birth and your nativity is of the land of Canaan; your father was an Amorite, and your mother an Hittite."

Then, in the fifth verse, he describes the condition of the nation when it was in Egypt, when nobody cared for it: Verses 5-16.
