the regions of Ephraim and Manasseh

Ephraim and Manasseh were two of the tribes in the northern part of Israel. Here the phrase "Ephraim and Manasseh" refers to the people who belonged to all ten of the northern tribes of Israel. See how you translated it in 2 Chronicles 30:1. AT: "the regions of the northern tribes of Israel" (See: rc://en/ta/man/translate/figs-synecdoche)

all the way to Zebulun

Zebulun was one of the tribes farthest in the north of Israel, but there were three other tribes that reached farther north.
