'Face of the Lord' in the Bible

'Three times in a year do all thy males appear before the face of the Lord Jehovah.

Arise, cry aloud in the night, At the beginning of the watches. Pour out as water thy heart, Over against the face of the Lord, Lift up unto Him thy hands, for the soul of thine infants, Who are feeble with hunger at the head of all out-places.

And thou, child, Prophet of the Highest Shalt thou be called; For thou shalt go before the face of the Lord, To prepare His ways.

who shall suffer justice -- destruction age-during -- from the face of the Lord, and from the glory of his strength,

because the eyes of the Lord are upon the righteous, and His ears -- to their supplication, and the face of the Lord is upon those doing evil;'
