También los hijos de Rubén y los hijos de Gad, y la media tribu de Manasés, pasaron armados delante de los hijos de Israel, según Moisés les había dicho.

John Gill's Bible Commentary
Ver. 12. And the children of Reuben, and the children of Gad, and half the tribe of Manasseh , etc.] Who were settled on the other side Jordan, in the countries taken from Sihon and Og: passed over armed before the children of Israel ; the rest of the tribes: as Moses spake unto them ; or ordered them, and as they promised they would, ( Numbers 32:17,20,21,27,29,32).
Matthew Henry Commentary
Verses 10-19 - The priests with the ark did not stir till ordered to move. Let none be weary of waiting, while they have the tokens of God's presence with them, even the ark of the covenant, though it be in the depths of adversity. Notice is taken of the honour put upon Joshua. Those ar feared in the best manner, and to the best purpose, who make it appea that God is with them, and that they set him before them.
