Israel is a luxuriant vine that puts forth his fruit. According to the abundance of his fruit he has multiplied his altars. As their land has prospered, they have adorned their sacred stones.
"A luxuriant vine ..." The figure of a vine as the representation of Israel abounds in both the Old Testament and the New Testament.  Christ extended it and applied it to the new Israel, his church, and also to himself, with whom the New Testament unequivocally identifies his church. "I am the true vine" (John 15:1).  The old Israel was the false vine; Christ and his church are the true vine.
