'Face of God' in the Bible

And Jacob called the name of the place Face of God; for I have seen God face to face, and my life is preserved.

And Jacob said, No, please, if now I have found grace in your sight, then receive my present at my hand. For therefore have I seen your face, as though I had seen the face of God, and you were pleased with me.

And now entreat the face of God, that He favor us. This has been by your hands, will He lift up your faces, says Jehovah of Hosts?
