Chapter 3 is a short chapter, just 5 verses, but it carries a powerful message. The Lord commands Hosea to take back his adulterous wife, so he buys her and tells her to come and live with him. It doesn’t say from whom he buys her, but possibly other men who have paid for her “services.” He is to buy her back, to “redeem” her specifically because “she is loved by another and is an adulteress.” He is commanded that his love for her be a metaphor of the Lord’s love for Israel, a love in spite of, not because of:
Love her as the Lord loves the Israelites, though they turn to other gods and love the sacred raisin cakes.”
If we put this in New Testament terms, we can say he loved Israel even when they were dead in their sins, and even when they were God’s enemies. Hosea pays to get his wife out of sin, even as the Lord paid the price of death to rescue us out of our sin. And notice Gomer could do nothing to make any of this happene because she was obviously owned by another. The Lord’s salvation is always thus, his initiative, his power, his price.
The last two verses are Messianic because the Israelites “will live many days” without any direction, but “afterward” they will “seek the Lord their God and David their king. They will come trembling to the Lord and to his blessings in the last days.” Since David is dead, one who comes in the line of David must be meant, and that would be Yeshua of Nazareth, the Messiah, the one Israel rejected. Whenever those days are, God seems to be saying, the people of Israel will eventually get it, and accept the one they rejected. I don’t think this could be interpreted to mean the Church. Paul does say that “all Israel will be saved.” Wouldn’t that be a great day, when Jews in mass come to accept Jesus as their Messiah, the son of David, the rightful air to the throne, their God and their Savior.
