Webster(i)
16 If any man shall see his brother sin a sin which is not to death, he shall ask, and he will give him life for them that sin not to death. There is a sin to death: I do not say that he shall pray for it.
17 All unrighteousness is sin: and there is a sin not to death.
18 We know that whoever is born of God, sinneth not; but he that is begotten of God, keepeth himself, and that wicked one toucheth him not.
