"...this was the gold from our mining: 'Thou mayest.' The American Standard translation 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 timshel—'Thou mayest'—that gives a choice. For if 'Thou mayest'—it is also true that 'Thou mayest not.' That makes a man great and that gives him stature with the gods, for in his weakness and his filth and his murder of his brother he has still the great choice. He can choose his course and fight it through and win."- John Steinbeck, "East of Eden"
