Charles Ellicott Commentary Joshua 22:7-8

"Now to the one half-tribe of Manasseh Moses had given [inheritance] in Bashan; but unto the other half gave Joshua among their brethren beyond the Jordan westward; moreover when Joshua sent them away unto their tents, he blessed them, and spake unto them, saying, Return with much wealth unto your tents, and with very much cattle, with silver, and with gold, and with brass, and with iron, and with very much raiment: divide the spoil of your enemies with your brethren." — Joshua 22:7-8 (ASV)

Joshua blesses the half tribe of Manasseh that lived on the west of Jordan.

(Joshua 22:7) When Joshua sent them away also to their tents, then he blessed them. It is noteworthy that of all the tribes of Israel who followed Joshua and remained with him, this half tribe alone is mentioned as receiving a special blessing. We cannot fail to observe that both in ancient times, and also among ourselves, the conduct of the two and a half tribes in choosing their inheritance on the east of Jordan has been regarded as exposing them to some blame. Historically, this is incorrect.

God delivered the land of Sihon and Og to Israel; someone must inherit it. Again, the true eastern boundary of Palestine is not the Jordan, but the mountain range of Gilead, which separates it from the desert that lies beyond. In reality, the two and a half tribes were as much in Palestine as the rest, only their position did not take advantage of that wonderful miracle by which Jordan was driven back, and the Israelites were enabled to strike at the heart of their Canaanite enemies.

They themselves, however, were compelled to cross the Jordan before they could obtain the nest they seemed to have won before crossing it—that they without us should not be made perfect. In the spiritual world, these two and a half tribes correspond to the people who received their inheritance from Moses (that is, from the law); the others are those who received nothing until they followed Joshua, i.e., the Captain of salvation, Jesus Christ, who gives rest to all.

When He came, His own people were divided, like the tribe of Manasseh. Some could not forsake Moses, a sacrifice which they thought He required of them; some gave up all and followed Him. Forgetting (Hebrew, M’nâsheh—i.e., Manasseh) the things that were behind, and reaching forth to the things before, they would take nothing but what He gave. These are the ones who receive special blessing from Him. (See Names on the Gates of Pearl—Manasseh, p. 165, etc.)
