What does the name Jacob mean?

Jacob is a old and important Old Testament Bible name. The name means "heel-grabber" or "he who supplants," because he was a twin, but born second, behind his twin brother Esau and grabbed Esau's heel as he was born. The name was prophetic- he did indeed supplant Esau via trickery and with the help of his mother. It may also mean "held by the heel,"
