When Saul led his armies, he said: "God will test you by a stream. Whoever drinks its water will not be of me; but those who do not drink shall be on my side. The only exception will be those who scoop up a palmful of water with their hands." And but for a few they all drank of its water. When they had crossed it, and those who believed with him, they said: "We have no strength to combat Goliath and his forces today. But those who believed they have to face their Lord, said: "Many a time has a small band defeated a large horde by the will of God. God is with those who are patient (and persevere)." 249 Accordingly, when they marched forward to fight with Goliath and his hosts, they prayed, "Our Lord, bless us with fortitude, make firm our foothold and give us victory over the unbelieving host." 250 And so by the command of God they defeated them. David killed Goliath, and God gave him kingship and wisdom, and imparted to him the knowledge of whatever He willed. Had it not been for God's repelling some people by means of others, the earth would have been filled with corruption. But God is bountiful to His creatures. 251 These are the messages of God. We recite them to you in all truth, as indeed you are one of the apostles. 252 ۞ Of these messengers, We have given something additional among them. There are some to whom God spoke directly and others He exalted in rank. We gave Jesus, son of Mary clear signs, and strengthened him with the holy spirit. Had God pleased, those who succeeded them would not have fought against one another after the clear signs had come to them. But they disagreed among themselves; some believed, while others did not. Yet had God willed, they would not have fought against one another; but God does whatever He wills. 253
