And when they were near to the land, which God had promised to Abraham and his seed, Moses chose a man from every tribe, and sent them to search out the land and the cities therein and the dwellers in the cities. At that time God revealed to him the Name which alone is able to save them that believe thereon; and Moses changed the name of Ausses the son of Navi, one of them that were sent, and named him Jesus; and so he sent them forth with the power of the Name, believing that he should receive them back safe and sound through the guidance of the Name, which came to pass.
