There was no Jesus in the old covenant. Hebron's prophecy mentions a warrior who conquers his enemies, conquers the promised land, and establishes the kingdom of God.
To understand it, you need to know something about the Israelites and their history. God God was one of the many cannabis dieties from the times when the Israelites believed in many gods. Yahweh was storming in the face of sending a heavenly war upon Israel's enemies. It was a war God. The Israelites were deprived of other gods, giving to Yahweh all the other attributes of God. For example, in creation it was God in charge of El, in hebraw Elohim. Even he was incorporated into the Jewish religion, referred to in scripture (not as a distinct God but as one of God's names), and as such a Messianic vision - to fight the one who would conquer enemies, conquer nations, and establish a new empire, at the price of blood I think.
Do you hear what it sounds like? How minor are those beliefs? The people who wrote them did not know anything about spiritual matters, and they wanted to fight. Even in the exodus the Israelites excused the extermination of the people they wanted to do despite their agreement with God. Their God to express their minds and hearts, is a God of thought.
Jesus is not at all the image of their Messiah, Jesus is a man of love, so great a love that there is no place for self-esteem within him. Putting Jesus in the hands of the nearest Israelites is like comparing homo sapiens with homo erectus.
The kingdom of God that Jesus spoke of is a state of mind, so here the Israelites and the Chrystains are far from the truth, no one will find that group following their beliefs.
