إِنْجِيلُ لُوقَا 11:34

سِرَاجُ ٱلْجَسَدِ هُوَ ٱلْعَيْنُ، فَمَتَى كَانَتْ عَيْنُكَ بَسِيطَةً فَجَسَدُكَ كُلُّهُ يَكُونُ نَيِّرًا، وَمَتَى كَانَتْ شِرِّيرَةً فَجَسَدُكَ يَكُونُ مُظْلِمًا.

The light of the body is the eye: therefore when thine eye is single, thy whole body also is full of light; but when thine eye is evil, thy body also is full of darkness.
