Joshua, the son of Nun, was a leader of the Hebrew people. He enjoyed the trust of Moses, who appointed him as his successor.
Through the power of his prayer, numerous miracles took place. He crossed the Jordan River by parting its waters, just as Moses had done at the Red Sea. He saw Archangel Michael himself bringing down the walls of Jericho with the sound of a trumpet. He also asked for the sun to stand still until victory over the Amorites was achieved, which was miraculously fulfilled. He led his people into the Promised Land, which he then divided among the tribes of Israel.
He fell asleep in peace at the age of 110.
The life and deeds of Joshua are described in the sixth book of the Old Testament. Furthermore, the Apostle Paul refers to him as an enlightened figure who guided the faithful toward the Kingdom of Heaven, just as Jesus Christ did.
As for the crossing of the Hebrews through the Jordan River, it is regarded as a prefiguration of the Holy Baptism.
Finally, concerning the city of Jericho, which was situated in a fertile valley and was the first to be conquered by Joshua, it was the homeland of Rahab. She was the only one to survive the destruction. A former prostitute who repented, she became an ancestor of the Messiah, who came into the world several centuries later.
