*14) This is an allusion to the countless favours with which Allah had blessed the Prophet David. He was an ordinary young man of the tribe of Judah, living at Bethlehem. In a campaign against the Philistines he slew the giant Goliath, the great enemy of Israel, and suddenly grew in esteem of the Israelites. With this event began his rise to prominence; so much so that after the death of Saul he was first elected king of Judah in Hebron (mod. AI-KhaliD, and then a few years later he was made king over aII the tribes of Israel. He took Jerusalem and made it the capital of the kingdom of Israel. It was under his leadership that for the first time in history a God-worshipping kingdom was established, whose boundaries extended from the Gulf of `Aqabah to the western banks of the River Euphrates. In addition to these favours, he was further graced with Divine bounties in the form of knowledge and wisdom, and the qualities of justice and mercy and devotion to the truth.
