Anaph (Aramaic) means face or nose, corresponding to the Hebrew aph (H639). The face represents the whole person — their presence, attention, and expression. In Daniel, the word appears in the context of the king's countenance changing in reaction to disturbing visions.
In biblical thought, the face (panim/anaph) symbolizes the fullness of personal presence. To seek God's face is to seek intimate relationship with Him. When the king's face changed at Daniel's words, it signaled inner transformation — even the most powerful human rulers are not immune to confrontation with divine reality.
