I already said the Torah blessings this morning. Why say them again?
It does feel like a repeat. At the start of the morning you said the blessings on Torah study. Now you are called up and say a different pair. The Tur (a law code from Spain, 1300s) and the Shulchan Aruch (the main code of Jewish law) both say to bless again, even if you said the morning blessing a moment ago.
Their reason is short. This blessing was set up out of respect for the Torah when it is read in public. So it is tied to the public reading itself, not to whether you already blessed.
Abudarham (a commentary on the prayers, Spain, around 1340) quotes the Rosh (Rabbeinu Asher, a leading rabbi in Germany and Spain, who died in 1327). The Rosh compares it to two other blessings set for the public reading: the one after the Torah, and the one the person reading the haftarah (the passage from the Prophets) says.
The Tur then tells of a case his brother, Rabbi Yechiel, raised. A man comes late, finishes the morning Torah blessing, and is called up right away. Is it strange to say two Torah blessings back to back? Rabbi Yechiel first thought one of them must be wasted. Then he asked their father, the Rosh, who said: he blesses, because the Sages did not make a distinction.
The Shulchan Aruch rules the same way. Even if you blessed for yourself and they call you up right away, you say "who chose us" again.
Tur, Orach Chaim 139,Shulchan Aruch, Orach Chaim 139:8,Abudarham, Torah ReadingWhat does "planted eternal life in us" mean, and why only after the reading?
The two blessings are not twins. Before you read, you say God chose us and gave us His Torah. After, you say God gave us "the Torah of truth" and "planted eternal life in us." Two classic writers explain the second blessing in different ways, and one of them also explains why it comes only after the reading.
One explanation is the Tur's. He reads the second blessing as naming two things. "The Torah of truth" is the Written Torah, the scroll you just heard. "Eternal life planted in us" is the Oral Torah, the teachings the Sages passed on. His proof is a verse in Kohelet: the words of the wise are like goads and like nails, planted firmly.
The Gemara has a related idea. Rabbi Yochanan says God made His covenant with Israel only for the sake of the oral teachings. He reads a verse as "on the mouth of these words I made a covenant with you."
Another explanation is Abudarham's. He knows the Tur's reading and records it, but starts somewhere else, with a verse in Mishlei: the Torah "is a tree of life to those who hold on to it." Before you read, you have not yet held it, so the first blessing does not say "eternal life." After you have held it and read from it, the blessing can. And since the verse calls the Torah a tree, the word "planted" fits.
That is also why Abudarham says each person called up should hold the scroll while blessing.
Tur, Orach Chaim 139,Kohelet 12:11,Gittin 60b,Mishlei 3:18,Abudarham, Torah ReadingWhy do I bless the reading if someone else is doing the reading?
It was not always this way. Once, the person called up read the passage aloud himself. The Shulchan Aruch (the main code of Jewish law) still has a rule for places that keep that custom: if he has not gone over the passage two or three times first, he should not go up.
At some point one skilled reader started reading for everyone. Abudarham (a commentary on the prayers, Spain, around 1340) records a first explanation from the first-fruits offering. The Mishnah says that long ago those who could recite the declaration did, and those who could not were fed the words. People stopped bringing first fruits out of embarrassment, so the Sages decreed that everyone is fed the words. In the same way, the leader reads with the one called up, so no one is embarrassed.
The Rosh (Rabbeinu Asher, a leading rabbi in Germany and Spain) does not accept that comparison. With first fruits, people stopped bringing them at all. Here, he says, embarrassment would only push people to learn the reading. He gives a practical reason instead. Not everyone knows the reading's tune and marks, and the congregation does not fulfill its duty through someone who does not. So the one who knows how reads.
That leaves a question. If the leader reads, what is the person called up doing? The Shulchan Aruch says he still reads along with the leader, but quietly, so that his blessing is not for nothing.
The Arukh HaShulchan (a code of law by Rabbi Yechiel Michel Epstein, around 1900) adds a simple point. Where the leader reads, the person called up must still bless. Otherwise, how would anyone know who had been called up to the Torah?
