In #genesis 48:1, an unnamed servant calls Joseph back to Israel. Could this be a prophecy of the Spirit calling Ephraim, the apostate northern Kingdom of Israel, back to the fold millennia later?
In v2, another unnamed servant tells Jacob of Joseph's coming. Could this be a prophecy to the rest of Jacob (aka Judah): "Prepare yourself. Ephraim is coming."?
I don't agree with some of the more fanciful "two-house theology" interpretations of prophecy and history, but there is an undeniable "two house" thread running throughout the Biblical prophecies and histories of Israel.
