Hos 2:18-20 And I will make for them a covenant on that day with the beasts of the field, the birds of the heavens, and the creeping things of the ground. And I will abolish the bow, the sword, and war from the land, and I will make you lie down in safety. And I will betroth you to me forever. I will betroth you to me in righteousness and in justice, in steadfast love and in mercy. I will betroth you to me in faithfulness. And you shall know the Lord.
Is 11 also indicates animals are part of the messianic covenant. This reference in Isaiah, even if only symbolic of humanity transformed, obviously points toward a messianic event. Mic 4:3-4 contains similar language speaking of a time of messianic rule when war would cease and people would live in peace and safety. There are no events in the past history of Israel or Judah that would really satisfy these prophecies although the post-exile rule of Zerubbabel, mentioned by Haggai, comes closest to its fulfillment. Betrothal implies a deep intimacy. Even the great reforms of post-exile Jewish society, overseen as they were by Persia, could only be described as a foreshadowing of a much greater fulfillment yet to be realized. Hosea talks about an intimacy that lasts forever. It also talks about knowing the YHWH. Yeshua (Jesus) made YHWH known to the Jews and, through the great commission given to the apostles, God’s Anointed One is made known to people everywhere. Through Christ God is made known to all. The indwelling Holy Spirit reveals God in a deeply personal and intimate way to believers of all walks of life. Born again believers are transformed. One could reasonably argue that the animals of Hos 2:18 symbolize the many peoples once separated from God who come to know Him now through Jesus Christ. Even these fulfillments pale in comparison to the ultimate hope held for the marriage of the lamb at the end of the age which John wrote so much about in the closing chapters of Revelation.
