The Hebrew noun panim (פָּנִים) is always plural in form and means face, countenance, or presence. It appears over 2,100 times — one of the most frequent nouns in Scripture. The phrase pene YHWH (the face of the LORD) carries the fullest theological weight.
To seek God's panim is the ultimate goal of the worshipper (Psalm 27:8). To experience His panim shining is the greatest blessing (Numbers 6:25). To be sent away from His panim is the deepest curse. The New Testament declares that "the glory of God" is seen "in the face of Jesus Christ" (2 Corinthians 4:6) — the ultimate fulfillment of panim theology.
