The Prophet King David was the son of Jesse of the tribe of Judah. He was a shepherd and psalm singer, who, for his fervent faith and courage in God, challenged the giant Goliath of the Philistines to single battle and defeated him with just three smooth stones from his sling, and the almighty power of the Living God in Whose honor and glory David fought. Saul, the first king of Israel, asked David to play his harp for him to soothe him, but later became jealous of David and spent years trying to kill him.
God took the kingdom of Israel away from King Saul because of his lack of faithful service to Him and gave it to David through the Prophet Samuel. King David ruled for many years in Israel and fought many battles to preserve Israel’s kingdom, but because his hands were bloody from these battles and other imperfections, God would not allow David to build Him a Temple, but reserved this for his son, King Solomon. King David was the ancestor of Jesus Christ according to the flesh (Matt 1:6, Luke 3:31). Most of the Book of Psalms is attributed to this mighty and faithful warrior of God, who remained a simple poet at heart.
