And so, how is this applied to the whole of judaism then?
Because if it is, as you are indicating, then the promises God made to the Jews have been broken by God. God (though the smoking pot and torch) walked through the two halves, not Abraham AND God.
No, the correct interpretation does not make God into a capricious God, like the god of the pagans.
All of God’s promises to the Jews were fulfilled in Christ.
