Then Joshua called the Reubenites, etc. - We have already seen that 40,000 men of the tribes of Reuben and Gad, and the half tribe of Manasseh, had passed over Jordan armed, with their brethren, according to their stipulation with Moses. The war being now concluded, Joshua assembles these warriors, and with commendations for their services and fidelity, he dismisses them, having first given them the most pious and suitable advices.

"And thou, Bethlehem Ephratah, too little to be among the thousands of Judah, out of thee shall come forth unto Me (one) [Pg 480] to be Ruler in Israel; and His goings forth are the times of old, the days of eternity."
