כד יְבָרֶכְךָ יְהוָה, וְיִשְׁמְרֶךָ. The LORD bless thee, and keep thee;
כה יָאֵר יְהוָה פָּנָיו אֵלֶיךָ, וִיחֻנֶּךָּ. The LORD make His face to shine upon thee, and be gracious unto thee
כו יִשָּׂא יְהוָה פָּנָיו אֵלֶיךָ, וְיָשֵׂם לְךָ שָׁלוֹם. The LORD lift up His countenance upon thee, and give thee peace.
כז וְשָׂמוּ אֶת-שְׁמִי, עַל-בְּנֵי יִשְׂרָאֵל; וַאֲנִי, אֲבָרְכֵם. . ( tanpa perantara !!! )
