When the Torah instructs the Kohanim to bless the congregation with Birkat Kohanim, we read two additional verses. One serves as the introduction to the blessing and the other as a conclusion. The introduction is:
The Lord spoke to Moses saying:Speak to Aaron and his sons, saying: This is how you shall bless the children of Israel, saying to them:May the Lord bless?
(Ibid Ibid, 22 ? 23)
Simply, God instructs Aharon and his descendants the Kohanim to bless the nation. But with the conclusion of this instruction we read another verse that raises a question regarding the identity of who is giving the blessing:
They shall bestow My Name upon the children of Israel, so that I will bless them.
(Ibid Ibid, 27)
So who is giving the blessing? God who says ?so that I will bless them?, or the Kohanim who were told ?This is how you should bless the children of Israel??
Actually, when you listen to the content of Birkat Kohanim itself, this question is easily answered. The Kohanim say to the congregation ?May the Lord bless you and watch over you?. So we see that the Kohanim bless the nation with God?s blessing. They do not create the blessing themselves. They just pass it on.
As to the literal meaning of the words ?so that I will bless them?, the great Jewish sages of the 1st century CE, Rabbi Akiva and Rabbi Yishmael, disagreed with one another. This dispute is mentioned in the Talmud Bavli (Tractate Chulin, daf 49). According to Rabbi Akiva, the meaning of these words is as we understand: It is not the Kohanim who bless the nation, but rather God provides His blessing to the nation. ?I will bless them?, with ?them? referring to the Jewish nation.
Rabbi Yishmael does not disagree with this concept since, as we have already shown, the blessing itself shows us that God is the one doing the blessing and not the Kohanim. And yet, he believes the words ?I will bless them? contain an additional meaning: The entire nation is blessed with God?s blessing by the Kohanim, but ? asks Rabbi Yishmael ? who blesses the Kohanim themselves? ??so that I will bless them? is the answer to this. God Himself blesses the Kohanim.
But are the Kohanim not included in the blessing of the entire nation? Do they not receive the blessing from God which they themselves bequeath to the congregation standing before them who hears their blessing? Why would we need another blessing in the form of ?I will bless them??
It seems that Rabbi Yishmael is teaching us an incredibly important lesson. Indeed, the Kohanim are blessed by the same Godly blessing which they pass on to the entire nation. But by performing this deed, by blessing the nation, they merit an additional blessing.
God?s blessing is given to all people. But whoever blesses others is privileged to receive an additional blessing. A person who wholeheartedly blesses another person is himself blessed with God?s blessing.
Sometimes it is hard for us to wholeheartedly bless another person. We might be worried that his success might harm our own. The Torah teaches us that the opposite is true. The more we bless, the more we are blessed. The more we love and the more we strive for others to be happy, the more loved and the happier we will be.
There is no blessing like God?s blessing, giving us abilities, desires, and hope. Whoever wants to merit receiving this blessing, must provide others with abilities, desires, and hope that we all need so badly.
