'Front part' in the Bible

If his hair has fallen off from the front part of his head, he is forehead bald. He is clean.

And the priest hath seen that which hath the plague after it hath been washed, and lo, the plague hath not changed its aspect, and the plague hath not spread, -- it is unclean; with fire thou dost burn it; it is a fretting in its back-part or in its front-part.
