A.T. Robertson Commentary 1 Peter 3:12

"For the eyes of the Lord are upon the righteous, And his ears unto their supplication: But the face of the Lord is upon them that do evil." — 1 Peter 3:12 (ASV)

Upon (επ). In the case of righteous (δικαιους, in the O.T. sense like δικαιον Λοτ in 2 Peter 2:7) for their good, but in the case of men "that do evil" (επ ποιουντας κακα, "upon men doing evil things") "the face of the Lord" (προσωπον κυριου) is not for their good, επ here approaching "against" in idea.
