also to clarify (and not for the last time) but among many reasons, including Jesus calling Himself Yahweh, He must be, because it is required in fulfillment of His own law. He views Himself as the husband and Israel as the wife. Paul elucidates in Romans that the only way to regather the "lost" sheep (pagan Israelites, of which most were) under the law is the husband were to die. If God "remarried" divorced Israelites, it was break the law.
