22 And the LORD spoke unto Moses, saying:
23 'Speak unto Aaron and unto his sons, saying: On this wise ye shall bless the children of Israel; ye shall say unto them:24 The LORD bless thee, and keep thee;
יְבָרֶכְךָ יְהוָה, וְיִשְׁמְרֶךָ.
Y’-varechecha Adonai v’yish-marechah.
25 The LORD make His face to shine upon thee, and be gracious unto thee;
יָאֵר יְהוָה פָּנָיו אֵלֶיךָ, וִיחֻנֶּךָּ.
Ya-air Adonai panav alechah veechu-nechah.
26 The LORD lift up His countenance upon thee, and give thee peace.
Yisah Adonai panav alechah v’ya-sem l’chah shalom.
27 So shall they put My name upon the children of Israel, and I will bless them.'
