And remember We took a covenant from the Children of Israel (to this effect): Worship none but Allah; treat with kindness your parents and kindred, and orphans and those in need; speak fair to the people; be steadfast in prayer; and practise regular charity. Then did ye turn back, except a few among you, and ye backslide (even now). 83 We made a covenant with you that you should not shed each other's blood or expel each other from your homeland. You accepted and bore witness to this covenant, 84 Yet, here you are, slaying one another and driving some of your own people from their homelands, aiding one another against them, committing sin and aggression; but if they came to you as captives, you would ransom them. Surely their very expulsion was unlawful for you. Do you believe in one part of the Book and deny another part of it? Those of you who act thus shall be rewarded with disgrace in this world and with a severe punishment on the Day of Resurrection. God is never unaware of what you do. 85 Those who have purchased the present life at the price of the world to come -- for them the chastisement shall not be lightened, neither shall they be helped. 86
