Augustine of Hippo
Patristic
A.D. 354–430
“"Keep Me, O Lord, as the apple of Thine eye": which seems very little and minute: yet by it is the sight of the eye directed, whereby the light is distinguished from the darkness; as by Christ's humanity, the divinity of the Judgment distinguishing between the righteous and sinners. "In the covering of Thy wings protect Me." In the defence of Thy love and mercy protect Me. "From the face of the ungodly who have troubled Me."”
