Origen
Patristic
c. A.D. 184–253
“After these things Jesus [Joshua] assembles the sons of Reuben and the sons of Gad and the half-tribe of Manasseh, who had served as soldiers with him to overcome the foes of the Israelites, and he dismisses them to go to their inheritance with certain gifts given to them, as it is written. Whereby this seems to indicate the mystery that "when the fullness of the nations will come in," they receive from the Lord Jesus what was promised to them, those who had been taught and instructed by Moses and who by prayers and entreaties brought aid to us who are placed in the contest. They have not yet "attained the promises," waiting so that our calling might also be fulfilled, as the apostle says. But now at last with the gifts they receive from Jesus they may attain the perfection that had been deferred for them so that each one may dwell in peace with every war and every battle ceasing.”
