...understanding the vehicles (venues) God commissions and uses to accomplish his plans.
The Hebrew origin is not with Abraham, Isaac, or Jacob. It is not even with the namesake (Eber, son of Shem, son of Noah). The origin of the things, people, and mind set of all things Hebrew is God.
So God talks like Jackie Mason?
No. Not hardly. But Jesus in a word for word translation said "Foxes have holes and birds of the air have nests but the Son of man doesn't have where to lay his head."
There are obviously variations, like the variation of the people who rejected Jesus as Messiah. The Jewish population in his day were not so universally against Christianity because they hadn't seen it yet. So (in the words of Michael Medved) Jews were about being Jewish then rather than about being non-Christian today.
A parenthetical thought... my only gripe with Messianic Jewish movements (plural) is that they tend to mimic the Jews who rejected Jesus too much. The yarmulke / head covering for males for example is a direct spite of Christian writings by their least favorite Christian (the turn coat Sha'ul b' Tarshish). So the Messianics erroneously use as their guides to "being Jewish" the branches of the Olive Tree that were cut off for unbelief (Romans 11:16-26).
God's plan progressed down through human history just as his revelation did, making superseding covenants with his people along the way. Like the valves in our heart that allow the blood to flow in only one direction, God's covenants disallow returning to previous covenants with him. This is the true meaning of the term "backslidden." It can and does refer to sliding back to sin or an earlier condition that is not good, but sliding back to a prior covenant with God displeases him no end. The biggest sin of the Jews in the wilderness (which just about got them all killed except Moses in Exodus 32) was not just the calf idol or the orgies but the turning back to the life they had before in the dawn of the Law of Moses on the Mountain of God.
Believer beware. 1 John 1:9 and 1 John 2:1 are true, but there could be a time when God is trying to show people something and you disobedience at that precise moment might well gain you a severe sentence from above. I am thinking of Moses striking the rock a second time to produce water for the thirsty people... God was trying to show the people that the Messiah is the Rock to turn to who would be struck once for all for all time. And Moses blew the prophetic model and it cost him the privilege of leading Israel into the Promised Land.
Prophetic of the Law of Moses and the Promised Land of Heaven.
