'Face' in the Bible

I said, O my God, shame keeps me from lifting up my face to you, my God: for our sins are increased higher than our heads and our evil-doing has come up to heaven.

From the days of our fathers till this day we have been great sinners; and for our sins, we and our kings and our priests have been given up into the hands of the kings of the lands, to the sword and to prison and to loss of goods and to shame of face, as it is this day.
