Joshua 18:9  (King James Version)
And the men went and passed through the land, and described it by cities into seven parts in a book, and came again to Joshua to the host at Shiloh.

The surveyors seem to have formed some kind of map of the country, as well as a description of it in writing. The Egyptians, from the situation of their fields, as annually overflowed by the Nile, acquired great skill in mensuration and land surveying; and some of the Israelites had, no doubt, learned these from them, without a knowledge of which they could not properly have divided the land. This is probably the first act of surveying on record.
