Jacob was a heel

Jacob, father of the 12 sons who produced the 12 tribes of Israel, got the Hebrew name Ya ‘aqov, which sounds like the Hebrew word for heel: ‘aqev (Genesis 25:26). It’s because he was born second, and came out holding onto the heel of his brother Esau. It’s perhaps just a coincidence that, at least as a young man, he grew up to become a heel who cheated his brother and his father. Strange and Mysterious Stuff in the Bible, p. 31.
