During their journeys across the wilderness, the twelve tribes
formed encampments at the different places where they halted
(Ex. 16:13; Num. 2:3). The diagram here given shows the position
of the different tribes and the form of the encampment during
the wanderings, according to Num. 1:53; 2:2-31; 3:29, 35, 38;

The area of the camp would be in all about 3 square miles.
After the Hebrews entered Israel, the camps then spoken of
were exclusively warlike (Josh. 11:5, 7; Judg. 5:19, 21; 7:1; 1
Sam. 29:1; 30:9, etc.).
