"There are ten horns that the Holy One, blessed be He, gave to Israel. The horn of Abraham, as it says, 'I will sing to my Beloved a song of love concerning His vineyard. My Beloved had a vineyard on a fertile hillside. He dug it up and cleared it of stones and planted it with the choicest vines. He built a watchtower in it and cut out a wine-press as well. Then He looked for a crop of good grapes, but it yielded only bad fruit. Now I will tell you what I am going to do to my vineyard: I will take away its hedge, and it will be destroyed; I will break down its wall, and it will be trampled. I will make it a wasteland, neither pruned nor cultivated, and briers and thorns will grow there. I will command the clouds not to rain on it.' (Isaiah 5:1-6)" The Horns of Israel (Genesis 22:13): "And behold, a ram caught in the thicket by its horns." The horn of Moses (Exodus 34:35): "Because the skin of his face shone, and he put a veil upon his face." The horn of prophecy (1 Samuel 2:1): "And Hannah prayed and said...My horn is exalted in the Lord." The horn of Torah (Habakkuk 3:4): "And rays streamed from His hand; and there was the hiding of His power." The horn of priesthood (Psalm 132:17): "There I will make a horn to bud for David; I have ordained a lamp for my anointed." The horn of Levi (1 Chronicles 25:5): "All these were the sons of Haman, the king’s seer in the words of God, to lift up the horn." The horn of Jerusalem (Psalm 22:22): "From the horns of the wild oxen You answered me." The horn of the King Messiah (1 Samuel 2:10): "The Lord shall judge the ends of the earth; and He shall give strength unto His king, and exalt the horn of His anointed." It is also said (Psalm 132:17), "There I will make a horn to bud for David." When the Jews sinned, these [horns] were taken from them and given to the gentiles, as it says (Daniel 7:24): "And as for the ten horns, out of this kingdom shall ten kings arise." The gentiles were compared to these beasts [represented by the horns], and as long as the horns of the gentiles are in existence, the horns of Israel are lowered, as it says (Lamentations 2:3): "He has cut off in fierce anger all the horn of Israel." But when the horns of Israel are lifted up in the future, in our days, the horns of the nations of the gentiles will be lowered, and the horns of Israel will be lifted up, as it says (Psalm 75:11): "And all the horns of the wicked will I cut off; but the horns of the righteous shall be exalted." The horns that lowered the horn of the righteous of the world will themselves be cut off.

In the future, the Messianic king will arise and renew the Davidic dynasty, restoring it to its initial sovereignty. He will build the Temple and gather the dispersed of Israel.
Then, in his days, the observance of all the statutes will return to their previous state. We will offer sacrifices, observe the Sabbatical and Jubilee years according to all their particulars as described by the Torah.
Anyone who does not believe in him or does not await his coming, denies not only the statements of the other prophets, but those of the Torah and Moses, our teacher. The Torah testified to his coming, as Deuteronomy 30:3-5 states:
God will bring back your captivity and have mercy upon you. He will again gather you from among the nations... Even if your Diaspora is at the ends of the heavens, God will gather you up from there... and bring you to the land....
These explicit words of the Torah include all the statements made by all the prophets.
