ISB ~ Matthew 6 v22

The eye is the lamp:An ancient metaphor (Tob 10:5; Prov 15:30; Sir 23:19). Jesus uses it to advocate generosity. Those with evil or unsound eyes are stingy with their belongings (Deut 15:9; Sir 14:8-10; cf. Mt 20:15); they are full of darkness (6:23). Those with sound eyes share their goods with the needy (4:7); they are filled with light.
