There are some, say the Talmud, who acquire their world in an hour 
and others who lose it in an hour. No example of the latter is more 
arresting and bewildering than the famous episode in this week’s parsha.
 The people have asked for water. God tells Moses to take a staff and 
speak to the rock and water will appear. This then follows:
He and Aaron gathered the assembly together in front of the rock and Moses said to them, ‘Listen, you rebels, must we bring you water out of this rock?’ Then Moses raised his arm and struck the rock twice with his staff. Water gushed out, and the community and their livestock drank. But the Lord said to Moses and Aaron, ‘Because you did not trust in Me enough to honour Me as holy in the sight of the Israelites, you will not bring this community into the land I give them.’
“Is this the Torah and this its reward?” we are tempted to say. What 
was Moses’ sin that it merited such punishment? In previous years I have
 expressed my view that Moses did not sin, nor was he punished. It was 
simply that each generation needs its own leaders. Moses was the right, 
indeed the only, leader capable of taking the Israelites out of Egypt. 
It needed another kind of leader and a different style of leadership, to
 take the next generation into the Promised Land.
This year, though, looking at the ethics of the Bible, it seems more 
appropriate to look at a different explanation, the one given by 
Maimonides in Shemoneh Perakim, the “Eight Chapters” that form the preface to his commentary to the Mishnah, tractate Avot, the Ethics of the Fathers.
In the course of these chapters Maimonides sets out a surprisingly 
contemporary account of Judaism as a training in “emotional 
intelligence.”
 Healthy emotions are essential to a good and happy life, but 
temperament is not something we choose. Some people just happen to be 
more patient or calm or generous-spirited or optimistic than others. 
Emotions were at one stage called the “passions,” a word that comes from
 the same root as “passive,” implying that they are feelings that happen
 to us rather reactions we chose to have. Despite this, Maimonides 
believed that with sufficient training, we could overcome our 
destructive emotions and reconfigure our affective life.
In general, Maimonides, like Aristotle, believed that emotional 
intelligence consists in striking a balance between excess and 
deficiency, too much and too little. Too much fear makes me a coward, 
too little makes me rash and foolhardy, taking unnecessary risks. The 
middle way is courage. There are, however, two exceptions, says 
Maimonides: pride and anger. Even a little pride (some sages suggested 
“an eighth of an eighth”) is too much. Likewise even a little anger is 
wrong.
That, says Maimonides, is why Moses was punished: because he lost his
 temper with the people when he said, “Listen, you rebels.” To be sure, 
there were other occasions on which he lost his temper – or at least 
looked as if he had. His reaction to the sin of the Golden Calf, which 
included smashing the tablets, was hardly eirenic or relaxed. But that 
case was different. The Israelites had committed a sin. God himself was 
threatening to destroy the people. Moses had to act decisively and with 
sufficient force to restore order to a people wildly out of control.
Here, though, the people had not sinned. They were thirsty. They 
needed water. God was not angry with them. Moses’ intemperate reaction 
was therefore wrong, says Maimonides. To be sure, anger is something to 
which we are all prone. But Moses was a leader, and a leader must be a 
role model. That is why Moses was punished so heavily for a failure that
 might have been more lightly punished in someone less exalted.
In addition, says Maimonides, by losing his temper Moses failed to 
respect the people and might have demoralized them. Knowing that Moses 
was God’s emissary, the people might have concluded that if Moses was 
angry with them, so too was God. Yet they had done no more than ask for 
water. Giving the people the impression that God was angry with them was
 a failure to sanctify God’s name. Thus one moment’s anger was 
sufficient to deprive Moses of the reward surely most precious to him, 
of seeing the culmination of his work by leading the people across the 
Jordan into the Promised Land.
The sages were outspoken in their critique of anger. They would 
thoroughly have approved of the modern concept of anger management. They
 did not like anger at all, and reserved some of their sharpest language
 to describe it.
“The life of those who can’t control their anger is not a life,” they
 said (Pesahim 113b). Resh Lakish said, “When a person becomes angry, if
 he is a sage his wisdom departs from him; if he is a prophet his 
prophecy departs from him” (Pesahim 66b). Maimonides said that when 
someone becomes angry it is as if he has become an idolater (Hilkhot 
Deot 2: 3).
What is dangerous about anger is that it causes us to lose control. 
It activates the most primitive part of the human brain that bypasses 
the neural circuitry we use when we reflect and choose on rational 
grounds. While in its grip we lose the ability to step back and judge 
the possible consequences of our actions. The result is that in a moment
 of irascibility we can do or say things we may regret for the rest of 
our lives.
For that reason, rules Maimonides (Hilkhot Deot 2: 3), there is no 
“middle way” when it comes to anger. Instead we must avoid it under any 
circumstance. We must go to the opposite extreme. Even when anger is 
justified, we must avoid it. There may be times when it is necessary to look as if we
 are angry. That is what Moses did when he saw the Israelites 
worshipping the Golden Calf, and broke the tablets of stone. Yet even 
then, says Maimonides, inwardly you should be calm.
The Orchot Tzadikim (15th century) notes that anger destroys
 personal relationships. Short-tempered people scare others, who 
therefore avoid coming close to them. Anger drives out the positive 
emotions – forgiveness, compassion, empathy and sensitivity. The result 
is that irascible people end up lonely, shunned and disappointed. Bad 
tempered people achieve nothing but their bad temper (Kiddushin 40b). 
They lose all else.
The classic role model of patience in the face of provocation was 
Hillel. The Talmud (Shabbat 31a) says that two people once made a wager 
with each other, saying, “He who makes Hillel angry shall receive four 
hundred zuz.” One said, “I will go and provoke him.” It was 
Erev Shabbat and Hillel was washing his hair. The man stood by the door 
of his house and called, “Is Hillel here, is Hillel here?”  Hillel robed
 himself and came out, saying, “My son, what do you seek?” “I have a 
question to ask,” he said. “Ask, my son,” replied Hillel. He said, “Why 
are the heads of the Babylonians round?” “My son, you ask a good 
question,’ said Hillel. “The reason is that they have no skilled 
midwives.”
The man left, paused, then returned, crying out, “Is Hillel here? Is 
Hillel here?” Again, Hillel robed and came out, saying, “My son, what do
 you seek?” “I have another question.” “Ask, my son.” “’Why are the eyes
 of the Palmyreans bleared?” Hillel replied, “My son, you ask a good 
question. The reason is that they live in sandy places.”
He left, waited, then came back a third time, calling, “Is Hillel 
here? Is Hillel here?” Again, Hillel robed and came out, saying, “My 
son, what do you seek?” “I have another question.” “Ask, my son.” “Why 
are the feet of Africans wide?” “My son, you ask a good question. The 
reason is that they live in watery marshes.”
“I have many questions to ask,” said the man, “but I am worried that 
you might become angry.” Hillel then robed himself and sat and said, 
“Ask all the questions you have to ask.” “Are you the Hillel who is 
called the nasi [leader, prince] of Israel?” “Yes,” said 
Hillel. “In that case, said the man, may there not be many like you in 
Israel.” “Why so, my son?” he asked. “Because I have just lost four 
hundred zuz because of you!” “Be careful of your moods,” said Hillel. “You may lose four hundred zuz and yet another four hundred zuz through Hillel, yet Hillel will not lose his temper.”
It was this quality of patience under provocation that was one of the
 factors, according to the Talmud (Eruvin 13b), that led the sages to 
rule according to the school of Hillel rather than that of Shammai.
The best way of defeating anger is to pause, stop, reflect, refrain, 
count to ten, and breathe deeply. If necessary, leave the room, go for a
 walk, meditate, or vent your toxic feelings alone. It is said that 
about one of the Rebbes of Lubavitch that whenever he felt angry, he 
would take down the Shulchan Arukh to see whether anger was permitted 
under the circumstances. By the time he had finished studying, his anger
 had disappeared.
The verdict of Judaism is simple: Either we defeat anger or anger will defeat us.
