Talmud - Nazir 66b נזיר ס״ו ב׳

Seize the opportunity and quickly recite a blessing over the cup of blessing for the Grace after Meals. And similarly, Rav Huna said to his son, Rabba: Seize the opportunity and recite a blessing.

The Gemara asks: Is this to say that one who recites a blessing is preferable to one who answers amen? But isn’t it taught in a baraita that Rabbi Yosei says: The one who answers amen is greater than the one who recites the blessing? And Rabbi Nehorai said to him: By Heavens, it is so. Know that this is true, as the military assistants [gulyarim] descend to the battlefield and initiate the war and the mighty follow them and prevail. The amen that follows a blessing is compared to the mighty who join the war after the assistants, illustrating that answering amen is more significant than reciting the initial blessing.

The Gemara responds: This is a dispute between tanna’im, as it is taught in a baraita: Both the one who recites a blessing and the one who answers amen are included among those who “stand up and bless” (Nehemiah 9:5), but one hurries to first reward the one who recites the blessing. This baraita apparently holds that reciting the blessing is greater than answering amen.

Rabbi Elazar said that Rabbi Ḥanina said: Torah scholars increase peace in the world, as it is stated: “And all your children [banayikh] shall be taught of the Lord, and great shall be the peace of your children” (Isaiah 54:13). The Sages interpreted this verse homiletically: Do not read it as: “Your children [banayikh],” but as: Your builders [bonayikh]. Torah scholars are those who build peace for their generation.
