The tribe of Ephraim - forty thousand and five hundred - Ephraim, as he was blessed beyond his eldest brother Manasseh, Genesis 48:20, so here he is increased by thousands more than Manasseh, and more than the whole tribe of Benjamin, and his blessing continued above his brother, Deuteronomy 33:17. And thus the prophecy, Genesis 48:19, was fulfilled: His younger brother (Ephraim) shall be greater than he, (Manasseh). No word of God can possibly fall to the ground: he alone sees the end from the beginning; his infinite wisdom embraces all occurrences, and it is his province alone to determine what is right, and to predict what himself has purposed to accomplish.
Those that were numbered of them, even of the tribe of Ephraim, were forty thousand and five hundred. 40,500 men. See Gill on Numbers 1:20.
Ephraim - Above 8000 more than Manasseh, towards the accomplishment of that promise, Genesis 48:20, which the devil in vain attempted to defeat by stirring up the men of Gath against them, 1-Chronicles 7:21-22.
