God formerly accepted the covenant of the children of Israel, and we appointed out of them twelve leaders: And God said, verily I am with you: If ye observe prayer, and give alms, and believe in my apostles, and assist them, and lend unto God on good usury, I will surely expiate your evil deeds from you, and I will lead you into gardens, wherein rivers flow: But he among you who disbelieveth after this, erreth from the strait path.
