East of Eden quote

"The American Standard translation [of the bible] orders men to triumph over sin, and you can call sin ignorance. The King James translation makes a promise in ‘Thou shalt,’ meaning that men will surely triumph over sin. But the Hebrew word, the word timshel — ‘Thou mayest’ — that gives a choice. 

It might be the most important word in the world. It says the way is open"..
