'Array' in the Bible

Your wives, your little ones, and your cattle shall abide in the land that Moses gave you on this side of the Jordan, but ye, all the valiant men, shall go over in array before your brethren and help them,

And the children of Reuben, and the children of Gad, and the half tribe of Manasseh, went over in array before the children of Israel, as Moses had spoken to them.
