Numbers 2:17-21

Then the tabernacle of the congregation shall set forward with the camp of the Levites in the midst of the camp: as they encamp, so shall they set forward, every man in his place by their standards.

On the west side shall be the standard of the camp of Ephraim according to their armies: and the captain of the sons of Ephraim shall be Elishama the son of Ammihud.

And his host, and those that were numbered of them, were forty thousand and five hundred.

And by him shall be the tribe of Manasseh: and the captain of the children of Manasseh shall be Gamaliel the son of Pedahzur.

And his host, and those that were numbered of them, were thirty and two thousand and two hundred.
