in Edition Clear Qur'an by Talal Itani / Al-Baqara (The Cow)

2:85But here you are, killing your own, and expelling a group of your own from their homes—conspiring against them in wrongdoing and hostility. And if they come to you as captives, you ransom them, although it was forbidden to you. Is it that you believe in part of the Scripture, and disbelieve in part? What is the reward for those among you who do that but humiliation in this life? And on the Day of Resurrection, they will be assigned to the most severe torment. God is not unaware of what you do.

2:249When Saul set out with the troops, he said, “God will be testing you with a river. Whoever drinks from it does not belong with me. But whoever does not drink from it, does belong with me, except for whoever scoops up a little with his hand.” But they drank from it, except for a few of them. Then, when he crossed it, he and those who believed with him, they said, “We have no strength to face Goliath and his troops today.” But those who knew that they would meet God said, “How many a small group has defeated a large group by God’s will. God is with the steadfast.”
