Is Jesus in the Old Testament? Does Jesus appear in the Old Testament? Does the Old Testament explicitly mention Jesus?

As the article explains Jesus existed as a prophetic promise, as a type and other examples in the Old Testament. He did not exist as flesh until the incarnation. The name of the second person of God is not Jesus.
Jesus is the flesh in which the second person took up residence at the incarnation.
Sometimes the New Testament talks about the human Jesus. Other times it talks about the second person of God within Jesus, his spirit.
God could not die, but the flesh he indwells could.
As with us our flesh and our spirit are separate and different. Born again is the cleansing of our spirit, but our flesh is still sinful. Glorified flesh is different than the flesh we now live in. Our flesh can be injured or die. Our spirit cannot.
The Hebrew concept says to make a promise that is absolutely sure to come about is the same thing as already existing. But it is still a promise yet to happen. That confuses people regarding Jesus Christ.
