Jamieson-Fausset-Brown on Numbers 32:20
Moses said unto them, If ye will do this thing--with sincerity and zeal.
go before the Lord to war--The phrase was used in allusion to the order of march in which the tribes of Reuben and Gad immediately preceded the ark (see on Num. 2:10-31), or to the passage over the Jordan, in which the ark stood in mid-channel, while all the tribes marched by in succession (Jos 3:4), of course including those of Reuben and Gad, so that, literally, they passed over before the Lord and before the rest of Israel (Jos 4:13).

Upon this they promise again (Num 32:25-27), through their spokesman (as the singular ויּאמר in Num 32:25, and the suffix in אדני in Num 32:27, clearly show), that they will fulfil his command. The use of the expression "before Jehovah," in the words, "go armed before Jehovah to war," in Num 3…
