The sedra of Tetsaveh, as commentators have noted, has one unusual feature: it is the only sedra from the beginning of Shemot to the end of Devarim that does not contain the name of Moses. Several interpretations have been offered:
The Vilna Gaon suggests that it is related to the fact that in most years it is read during the week in which the seventh of Adar falls: the day of Moses' death. During this week we sense the loss of the greatest leader in Jewish history - and his absence from Tetsaveh expresses that loss.
The Baal HaTurim relates it to Moses' plea, in next week's sedra, for G-d to forgive Israel. "If not," says Moses, "blot me out of the book you have written" (32: 32). There is a principle that "The curse of a sage comes true, even if it was conditional" (Makkot 11a). Thus for one week his name was "blotted out" from the Torah.
The Paneach Raza relates it to another principle: "There is no anger that does not leave an impression" When Moses, for the last time, declined G-d's invitation to lead the Jewish people out of Egypt, saying "Please send someone else", G-d "became angry with Moses" (Ex. 4: 13-14) and told him that his brother Aaron would accompany him. For that reason Moses forfeited the role he might otherwise have had, of becoming the first of Israel's priests, a role that went instead to Aaron. That is why he is missing from the sedra of Tetsaveh which is dedicated to the role of the Cohen.
All three explanations focus on an absence. However, perhaps the simplest explanation is that Tetsaveh is dedicated to a presence, one that had a decisive influence on Judaism and Jewish history.
Judaism is unusual in that it recognises not one form of religious leadership but two: the navi and Cohen, the prophet and the priest. The figure of the prophet has always captured the imagination. He (or she) is a person of drama, "speaking truth to power", unafraid to challenge kings and courts or society as a whole in the name of high, even utopian ideals. No other type of religious personality has had the impact as the prophets of Israel, of whom the greatest was Moses. The priests, by contrast, were for the most part quieter figures, a-political, who served in the sanctuary rather than in the spotlight of political debate. Yet they, no less than the prophets, sustained Israel as a holy nation. Indeed, though Israel were summoned to become "a kingdom of priests" they were never called on to be a people of prophets (Moses said, "Would that all G-d's people were prophets”, but this was a wish, not a reality).
Let us therefore consider some of the differences between a prophet and a priest:
• The role of priest was dynastic. It passed from father to son. The role of prophet was not dynastic. Moses' own sons did not succeed him; Joshua, his disciple did.
• The task of the priest was related to his office. It was not inherently personal or charismatic. The prophets, by contrast, each imparted their own personality. "No two prophets had the same style" (This, incidentally, is why there were prophetesses but no priestesses: this corresponds to the difference between formal office and personal authority. See R. Eliyahu Bakshi-Doron, Responsa Binyan Av, I: 65).
• The priests wore a special uniform; the prophets did not.
• There are rules of kavod (honour) due to a Cohen. There are no corresponding rules for the honour due to a prophet. A prophet is honoured by being listened to, not by formal protocols of respect.
• The priests were removed from the people. They served in the Temple. They were not allowed to become defiled. There were restrictions on whom they might marry. The prophet, by contrast, was usually part of the people. He might be a shepherd like Moses or Amos, or a farmer like Elisha. Until the word or vision came, there was nothing special in his work or social class.
• The priest offered up sacrifices in silence. The prophet served G-d through the word.
• They lived in two different modes of time. The priest functioned in cyclical time - the day (or week or month) that is like yesterday or tomorrow. The prophet lived in covenantal (sometimes inaccurately called linear) time - the today that is radically unlike yesterday or tomorrow. The service of the priest never changed; that of the prophet was constantly changing. Another way of putting it is to say that the priest worked to sanctify nature, the prophet to respond to history.
• Thus the priest represents the principle of structure in Jewish life, while the prophet represents spontaneity.
Command the Israelites to bring you clear oil of pressed olives, to keep the lamp constantly burning in the tent of meeting, outside the curtain that is in front of the Testimony, Aaron and his sons shall keep the lamps burning before the Lord from evening to morning. This is to be a lasting ordinance among the Israelites for the generations to come.
