John 9:3-5

Young's Literal Translation

³ Jesus answered, `Neither did this one sin nor his parents, but that the works of God may be manifested in him;

⁴ it behoveth me to be working the works of Him who sent me while it is day; night doth come, when no one is able to work: --

⁵ when I am in the world, I am a light of the world.'
