In ancient Israel, it was commonly believed that a child was born with disabilities because of the sin of one of his parents. This was not the teaching of the law of Moses. In this exchange, the Pharisees were sinners because they saw the power of Jesus and did not worship him. (See: [[rc://en/tw/dict/bible/kt/sin]] and [[rc://en/tw/dict/bible/kt/lawofmoses]])
John uses this phrase seven times in his gospel. It is the same words used by God, when he revealed himself and his name Yahweh at the burning bush. The name "Yahweh" can be translated as "I am."
Light is a common image in Scripture used to represent righteousness. Light is also used to show the path of righteousness and to show righteous living. Darkness is often used as images representing sin or unrighteousness. (See: [[rc://en/tw/dict/bible/other/light]], [[rc://en/tw/dict/bible/kt/righteous]], [[rc://en/tw/dict/bible/other/darkness]], [[rc://en/tw/dict/bible/kt/sin]] and [[rc://en/tw/dict/bible/kt/righteous]])
The Pharisees considered Jesus making the mud to be "work" and in violation of the laws regarding the Sabbath. (See: [[rc://en/tw/dict/bible/kt/sabbath]])

##### Sight #####
This chapter records the events of a man who was born without sight. Jesus also uses these events as a metaphor. In [John 9:39-40](./39.md), the Pharisees are called blind because they are unable to see the truth in front of them. (See: [[rc://en/ta/man/translate/figs-metaphor]])
#### Other possible translation difficulties in this chapter ####
Jesus refers to himself as the "Son of Man" in this passage. Some languages may not allow a person to refer to himself in the third person. (See: [[rc://en/tw/dict/bible/kt/sonofman]])
