Ezekiel 21:19

Also, thou son of man, appoint thee two ways, by means of a drawing or map showing a road branching off in two directions, that the sword of the king of Babylon may come, as his armies advanced to the conquest, both twain shall come forth out of one land, and choose thou a place, a finger-post, or pointer, to guide men aright; choose it at the head of the way to the city, placing it at the parting of the ways, so that no mistake as to directions would be possible.
