The instruction "You shall invest him with some of your authority, that all the congregation of the people of Israel may obey" was given in connection with the appointment of Joshua to succeed Moses. In the book of Numbers chapter 27, God commanded Moses to climb a mountain to see the land of Canaan that God was giving to the Israelites. God also told Moses that he would not be the one to lead the Israelites into the Promised Land because he had disobeyed God at the waters of Meribah. So, Moses asked God to appoint a successor to lead the Israelites after he was gone. God then told Moses to take Joshua, his assistant, and lay his hands on him, and "invest him with some of your authority, that all the congregation of the people of Israel may obey" (Numbers 27:20). Moses obeyed God's command and laid his hands on Joshua, passing some of his authority to him. Therefore, the correct answer to the question is that the instruction "You shall invest him with some of your authority, that all the congregation of the people of Israel may obey" was given in connection with the appointment of Joshua to succeed Moses as the leader of the Israelites.
