וַאֲבָֽרֲכָה֙ מְבָ֣רְכֶ֔יךָ וּמְקַלֶּלְךָ֖ אָאֹ֑ר וְנִבְרְכ֣וּ בְךָ֔ כֹּ֖ל מִשְׁפְּחֹ֥ת הָאֲדָמָֽה׃
너를 축복하는 자에게는 내가 복을 내리고 너를 저주하는 자에게는 내가 저주하리니 땅의 모든 족속이 너를 인하여 복을 얻을 것이니라 하신지라
Mishneh Torah, Prayer and the Priestly Blessing
The priest who does not go up to the platform to bless the people, although he has neglected to fulfill one affirmative precept, is accounted as having transgressed three affirmative precepts, for it is said, "On this wise ye shall bless the children of Israel"; "Ye shall say unto them"; "So shall they put my name" (Numbers 6:22-27). Any priest who does not bless the people is not blessed. Every priest who blesses them is blessed, for it is said, "I will bless them that bless thee" (Genesis 12:3). Blessed be the All-Merciful who hath helped us.
