When Joshua the prophet was born?

Answer 1

Moses died at the end of the 40-year period of wandering in the wilderness about 1405BC ( thus making Moses born about 1525BC) when he transferred the leadership to Joshua:-

Deu 31:1-2 KJV And Moses went and spake these words unto all Israel. [v. 2] And he said unto them, I am an hundred and twenty years old this day; I can no more go out and come in: also the LORD hath said unto me, Thou [Moses] shalt not go over this Jordan.

Deu 31:7 KJV And Moses called unto Joshua, and said unto him in the sight of all Israel, Be strong and of a good courage: for thou [Joshua] must go with this people unto the land which the LORD hath sworn unto their fathers to give them; and thou shalt cause them to inherit it.

Deu 34:7-9 KJV And Moses was an hundred and twenty years old when he died: his eye was not dim, nor his natural force abated. [v. 8] And the children of Israel wept for Moses in the plains of Moab thirty days: so the days of weeping and mourning for Moses were ended. [v. 9] And Joshua the son of Nun was full of the spirit of wisdom; for Moses had laid his hands upon him: and the children of Israel hearkened unto him, and did as the LORD commanded Moses.

Working backwards from Joshua 24:29 when Joshua died at 110 to this leadership change makes Joshua about 90 when this happened, so this would make him born about 1495BC.
