“Take Joshua the son of Nun, a man in whom is the Spirit, and lay your hand on him” (v18). Moses had led the people out of Egypt and through 40 years in the wilderness, and he was about to die. Like the entire generation of Israelites that were adults when they left Egypt, Moses would not enter the Promised Land (26:65). That original generation failed to believe that God could provide for them and conquer their enemies, except for Joshua and Caleb, who believed.
“And he laid his hands on him and commissioned him” (v23). Joshua was chosen to lead not because of his battle expertise or eloquence but because he had faith in what God could do.
