And the children of Israel shall pitch their tents, every man
 by his own camp
 There were four, unless every tribe was a camp, and so then there were twelve camps, besides the camp of the Levites: the Targum of Jonathan is, 
``by the house of his troop,''the regiment to which he belonged, every tribe or camp having various troops or regiments in it:
 and every man by his own standard throughout their hosts;
 there were four standards, and three tribes to each standard, which were placed east, west, north, and south of the tabernacle, as is at large described in the following chapter.
