Tafsiran Bilangan 27:18: Rashi, Avi Ezer, Kli Yakar & Sforno

קח לך TAKE TO THEE [JOSHUA] — take him through fine words, saying,“Fortunate are you that you have merited to lead the children of the Omnipresent!” (cf. Sifrei Bamidbar 92 on 11:16).

That which has a spirit in it, and every living person has a spirit within them, etc.Only an explanation (or interpretation) by the spirit of wisdom and knowledge can reveal this. Therefore, it is said, "Because there was another spirit with him." The verse uses concise language in a place where the matter can be understood on its own. We have also become accustomed to saying to a person, "I will repay you for this and this," or "After this and this," or "Before this and this." And I acknowledge that everyone will understand the statement, "The judgment of the day of the marketplace," which is in concise language in a known month. Therefore, they shortened their language. And so it is with the judgment of all languages.

“And you shall lay your hand upon him.” The phrase suggests one hand, yet in the actual event it is written, and he laid his hands upon him. Rashi explains that Moses did more than he was commanded, etc. According to his words, it is difficult to understand how Moses transgressed the prohibition of “do not add” [to the commandments]. We find another similar laying of hands where it says, And he shall lay his hand upon the head of the burnt offering (Leviticus 1:4). This suggests one hand, yet in practice it is written, And Aaron shall lay both his hands upon the head of the goat (Leviticus 16:21). Above, in the portion of Vayikra, we explained that it is all one matter, because the leaders of the people need to accept upon themselves to be an atonement and guilt offering for all the people, as it is written, And I will make them heads over you (Deuteronomy 1:13). Our Sages learned from here (Devarim Rabbah 1:9) that the guilt of the people is dependent upon their leaders. Just as the laying of a hand upon a sacrifice is to place some blemish and fault of the one who lays hands onto the one receiving the hands [the sacrifice], so too this laying of hands was to place some blemish and fault of all Israel upon their leaders, saying that the guilt of the people is dependent upon them. Now, for the typical sacrifice of a sinner, there are two types of hand-laying, because the sin of the sinner in his act of transgression is twofold, as there is no action without the thought that precedes the action. Therefore, regarding the scapegoat it says, And Aaron shall lay both his hands, because it comes to atone for both the sin of action and thought. But the burnt offering comes to atone only for the sin of thought; therefore it says, And he shall lay his hand upon the head of the burnt offering, suggesting just one hand.

לך [TAKE] TO THEE — take one who has been examined by you, the one with whom you are familiar.
