"The face denotes the presence of the person, and the countenance denotes the expression of the person.  To lift up one's countenance upon a person means to confirm, assure, promise, and give everything to that person.  Jesus, the Son, came as the face of God, and the Holy Spirit comes as the countenance of God.  When the Triune God is dispensed into us, we have the face of the Triune God and also His countenance.  Eventually, we are kept in the Triune God, the Triune God becomes grace to us, and we have peace."

Numbers 6:26 footnote 1
