1. Verse 246: إِذْ قَالُوا لِنَبِيٍّ لَّهُمُ ابْعَثْ لَنَا مَلِكًا نُّقَاتِلْ فِي سَبِيلِ اللَّهِ (When they said to a prophet of theirs: "Send us a king so that we may fight in the way of Allah)."
These people from the Bani Isra'il had abandoned the injunctions given by Allah Almighty. When the infidel Amalekites were made to rule over them, they began thinking about correcting the situation. The name of the prophet mentioned here is Samuel (Arabic: Hebrew: Shemuel).
Verse 248: The story of Talut and Jalut
The Bani Isra'il used to have the legacy of a wooden chest (also identified as the Ark of the Covenant). Moses and other prophets of Bani Isra'il would keep this chest in the frontline of the battlefield. Its barakah بَرَکَہ (blessing, benediction) used to give them victory. When )Jalut: Goliath) overcame Bani Isra'il, he took this chest away with him. When Allah Almighty willed the return of the chest, it so happened that the infidels were struck by some epidemic or calamity at places where they carried this chest. Five cities were turned desolate. Nonplussed, they loaded it on two bullocks and drove them off. Then, the angels took control of the bullocks and made it reach Talut's doorsteps. (Talut is the Qur'anic name of the king known in the Bible as Saul) When the Bani Isra'il saw this sign, they believed in the kingdom of Talut, who then mounted an attack on Jalut while the weather was very hot.
