Several of
Hillel's teachings are explained by comparison to what
Shammai (
Hillel's principal adversary, rival or disputant) taught on the same subject. Some of Hillel the Elder's teachings remain commonly known. However, at least two other notable
Hillels came after him, and some scholars have suggested that some sayings attributed to "Hillel" may have originated from them. The saying of Hillel that introduces the collection of his maxims in the Mishnaic treatise
Pirkei Avot mentions
Aaron HaKohen (the
high priest) as the great model to be imitated in his love of peace, in his love for his fellow man, and in his leading mankind to a knowledge of the Law (Pirkei Avoth 1:12). In mentioning these characteristics, which the
aggadah attributes to Moses' brother, Hillel stated his own prominent virtues. He considered "love of his fellow man" the kernel of Jewish teaching.
The Oral Law A gentile came to Shammai and asked how many Torahs there were. Shammai answered "two": the written Torah and the Oral Torah. The gentile did not believe him and asked to be converted on condition he only had to learn the written Torah. Shammai sent him away. The gentile went to Hillel who converted him and then started teaching him the Torah(s). He started with teaching him the
Hebrew alphabet: the first letter is "Aleph", the next letter is "bet", etc. The next day, Hillel taught him: the first letter is "Tav", the next letter is "shin", etc. (the alphabet backwards). The convert said that this was different to what he had been taught the previous day. Hillel replied that in the same way you need an oral teaching to learn the written alphabet, so you need an oral explanation to understand the written Torah.
The Golden Rule The comparative response to the challenge of a prospective convert who asked that the Torah be explained to him while he stood on one foot, illustrates the character differences between
Shammai and Hillel. Shammai dismissed the man. Hillel gently chided the man: This rule is commonly called the
Golden Rule, which has been practiced to this day by a wide range of peoples, including through
Confucianism,
Christianity, the
Enlightenment Age, and
Kant's
categorical imperative.
Love of peace The exhortation to love peace emanated from Hillel's most characteristic traits—his proverbial meekness and mildness—as in the saying: Hillel's gentleness and patience are illustrated in an anecdote that describes how two men made a bet on the question of whether Hillel could be made angry. Although they questioned him and made insulting allusions to his Babylonian origin, they were unsuccessful. The third part contains the admonition to postpone no duty, the same admonition he gave with reference to study: "Say not, 'When I have free time I shall study'; for you may perhaps never have any free time." Man should not appear different from others in his outward deportment; he should always regard himself as a part of the whole, thereby showing that love of man Hillel taught. The feeling of love for one's neighbor shows itself also in his exhortation (Avot 2:4). How far his love of man went may be seen from an example that shows that benevolence must be given with regard to the needs of the poor. Thus, Hillel provided a riding horse to a man of good family who became poor, in order that he not be deprived of his customary physical exercise; he also gave him a slave, that he might be served.
Other maxims • "Do not separate yourself from the community; do not believe in yourself until the day you die; do not judge your fellow until you have reached their place; do not say something inappropriate, for it will then be appropriated; and do not say, 'When I am free I will study,' for perhaps you will not become free." • "Whosoever destroys one soul, it is as though he had destroyed an entire world. And whosoever saves a life, it is as though he had saved an entire world." • "A name gained is a name lost." • "Where there are no men, strive to be a man!" • "My humiliation is my exaltation; my exaltation is my humiliation."
The study of Torah The many anecdotes according to which Hillel made proselytes, correspond to the third part of his maxim: "Bring men to the Law." A later source (
Avot of Rabbi Nathan) gives the following explanation of the teaching: Hillel stood in the gate of Jerusalem one day and saw the people on their way to work. "How much," he asked, "will you earn to-day?" One said: "A
denarius"; the second: "Two denarii." "What will you do with the money?" he inquired. "We will provide for the necessities of life." Then said he to them: "Would you not rather come and make the
Torah your possession, that you may possess both this and the future world?" This narrative has the same points as the epigrammatic group of Hillel's sayings (Avot 2:7) commencing: "The more flesh, the more worms," and closing with the words: "Whoever has acquired the words of the Law has acquired the life of the world to come." In an
Aramaic saying Hillel sounds a warning against neglect of study or its abuse for selfish purposes: "Whoever would make a name (i.e. glory) loses the name; he who increases not [his knowledge] decreases; whoever learns not [in
Avot of Rabbi Nathan 12: "who does not serve the wise and learn"] is worthy of death; whoever exploits for his own use the crown (of Torah) perishes" (Avot 1:13). ==Halachic teachings==
