"HaShem is my Shepherd;.." (Psalms 23).

"So the Lord guided them alone, and there was no alien deity with Him" (Deut. 32:12). God guided the children of Israel safely and alone in the wilderness of the nations, to eternal joy and happiness.

"He chose David also His servant, and took him from the sheepfolds; From following the ewes that give suck He brought him, to be shepherd over Jacob His people, and Israel His inheritance. So he shepherded them according to the integrity of his heart; and lead them by the skilfulness of his hands" (Psalms 78:70-72).

WHEN MOSES ASKS FOR A SUCCESSOR; Moses spoke to the Lord, saying: "Let the Lord, the God of spirits of all flesh, appoint a man over the congregation, who will go forth before them and come before them, who will lead them out and bring them in, so that the congregation of the Lord will not be like sheep without a shepherd." (Numbers 27:15-17).

Of all the ways Moses could have adressed God, he chose this one; ”the God of spirits of all flesh.” Instead of referring to God’s omnipotence of wisdom, HE SPOKE OF GOD’S KNOWLEDGE OF THE INTRICACIES OF THE HUMAN MIND AND PERSONALITY, of God’s knowledge that every person has his own virtues and foibles, and that the best way to lead is to understand the needs of every follower – and accept their shortcomings. Moses thus implied that the sort of leader he wanted to succeed him was one who, as much as humaly possible, embodied these Divine characteristics so as to accommodate the individuals who comprise the nation (Rashi).

Moses listed the qualifications he wanted in the leader, all of which reveal a  concern for Israel. The leader should go out before them, leading them in battle as Moses had done in the wars of Sihon and Og, and as Joshua had done in repelling Amalek (Ex. 17:10-13), and not remain in the backlines, leaving the risks to others.

"The Lord said to Moses, "Take for yourself Joshua the son of Nun, a man of spirit,.." (v18). Even after Joshua became the leader of Israel, he was to realize that he was to remain subservient to Moses, that he must always guide himself by what Moses would have done in a given situation, for a leader of Israel is always a link in the tradition that has come down to us from leader to leader, beginning with Moses and Joshua.

When Moses takes leave (Deut. 31:1-8), he made it clear that God Himself would go before them and annihilate their enemies. True, Joshua would be their leader, but the true power would be God’; Joshua’s presence would be with them in fulfillment of God’s command, not because he had any independent power of his own (Sforno).
