'Face' in the Bible

Better is sorrow than laughter, For by the sadness of the face the heart becometh better.

Who is as the wise? and who knoweth the interpretation of a thing? The wisdom of man causeth his face to shine, and the hardness of his face is changed.

If the iron hath been blunt, And he the face hath not sharpened, Then doth he increase strength, And wisdom is advantageous to make right.

Send forth thy bread on the face of the waters, For in the multitude of the days thou dost find it.
