Shemot 33:14

ויאמר פני ילכו AND HE SAID, MY FACE SHALL GO WITH THEE Understand this as the Targum renders it: My Shechinah will go — I will no more send an angel with you, but I Myself will go. פנים here has the sense of “Self” as in (II Samuel 17:11) “and that thou go in the battle in thine own person (פניך)”.

וַיֹּאמַ֑ר פָּנַ֥י יֵלֵ֖כוּ וַהֲנִחֹ֥תִי לָֽךְ׃

And he said, My presence shall go with thee, and I will give thee rest.
