Numbers 13

And the same [Moses] by divine inspiration foresaw the name Jesus very clearly and again also endowed this with special privilege. The name of Jesus, which had never been uttered among men before it was made known to Moses, Moses applied first to this one alone. He knew that Joshua, again as a type and a symbol, would receive the rule over all after Moses' death. His successor, at any rate, had never before used the title Jesus. He had been called by another name, Auses, which his parents had bestowed upon him. Moses himself proclaims Jesus, as a privilege of honor far greater than a royal crown, giving him the name because Jesus, the son of Nave, himself bore a resemblance to our Savior, who alone, after Moses and the completion of the symbolic worship transmitted by him, received the rule of true and pure religion.

Later on, a sacred vine put forth a cluster of grapes that was prophetic. To those who had been led by the Educator to a place of rest after their wanderings it was a sign, for the great cluster of grapes is the Word crushed on our account. The Word desired that the "blood of the grape" be mixed with water as a symbol that his own blood is an integral element in salvation.
