What does Genesis 48:14 mean?

But Jacob reached out and crossed his arms, putting his right hand on Ephraim, the younger, and his left hand on Manasseh. He blessed Joseph and said, 'The God my fathers Abraham and Isaac walked with, the God who’s taken care of me all my life,' Genesis 48:14 - Modern Text Bible

(Jacob, guided by God, chose to bless the younger son over the older, showing that God’s plans don’t always follow human expectations. He began his blessing by honoring the God who had always been with him.)
