What goes with that Vulcan sign ...
May Adonai bless you and guard you –
יְבָרֶכְךָ יהוה, וְיִשְׁמְרֶךָ
(Yevhārēkh-khā Adhōnāy veyishmerēkhā ...)
May Adonai make His face shed light upon you and be gracious unto you –
יָאֵר יהוה פָּנָיו אֵלֶיךָ, וִיחֻנֶּךָּ
("Yāʾēr Adhōnāy pānāw ēlekhā viḥunnékkā ...)
May Adonai lift up His face unto you and give you peace –
יִשָּׂא יהוה פָּנָיו אֵלֶיךָ, וְיָשֵׂם לְךָ שָׁלוֹם
("Yissā Adhōnāy pānāw ēlekhā viyāsēm lekhā shālōm.")
