Doubtless there was somewhat prophetical in the blessing of Joshua, as there was in all the blessings of the patriarchs, when taking leave: see Genesis 49:1; Deuteronomy 33:1.
Joshua 22:6-9
6 So Joshua blessed them, and sent them away: and they went unto their tents.
7 Now to the one half of the tribe of Manasseh Moses had given possession in Bashan: but unto the other half thereof gave Joshua among their brethren on this side Jordan westward. And when Joshua sent them away also unto their tents, then he blessed them,
8 And he spake unto them, saying, Return with much riches 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.
9 And the children of Reuben and the children of Gad and the half tribe of Manasseh returned, and departed from the children of Israel out of Shiloh, which is in the land of Canaan, to go unto the country of Gilead, to the land of their possession, whereof they were possessed, according to the word of the LORD by the hand of Moses.
