2:247
And said to them their Prophet, "Indeed, Allah (has) surely raised for you Talut (as) a king." They said, How can be for him the kingship over us, while we (are) more entitled to kingship than him, and not he has been given abundance of [the] wealth?" He said, "Indeed, Allah has chosen him over you and increased him abundantly in [the] knowledge and [the] physique. And Allah gives His kingdom (to) whom He wills. And Allah (is) All-Encompassing, All-Knowing."

2:249
Then when set out Talut with the forces he said, "Indeed, Allah will test you with a river. So whoever drinks from it then he is not from me, and whoever (does) not taste it then indeed, he (is) from me except whoever takes (in the) hollow (of) his hand." Then they drank from it except a few of them. Then when he crossed it, he and those who believed with him, they said, "No strength for us today against Jalut and his troops." Said those who were certain that they (would) meet Allah, "How many of a company small overcame a company large by (the) permission (of) Allah. And Allah (is) with the patient ones."
