The prophet expresses Israel’s essence and also transmits messages from the Holy One, blessed be He. The prophet’s power is dependent on the children of Israel, and he needs them more than they need him.

The prophet serves as Israel’s mouth [expressing the truths that make up their spiritual essence]. The prophet’s abilities are therefore dependent on the children of Israel’s service of God. As it is written: “A prophet from your midst…the Lord your God will establish for you” (Deuteronomy 18:15). More than Israel needs the prophet, the prophet needs them. (Rabbi Yehuda Aryeh Leib Alter, Sefat Emet, Balak 5649)
