What does 1 Samuel 17:20 mean?
The Philistines have gathered against Israel for war near the Valley of Elah (1 Samuel 17:1–3). Jesse, an elderly man living in Bethlehem, has eight sons. Three of those sons are at the field of battle with King Saul (1 Samuel 17:12–14). His youngest son, David, tends his father's sheep and also serves King Saul (1 Samuel 17:15). Due to Saul's flagrant disobedience, God rejected him as king (1 Kings 15:22–29). God sent the prophet Samuel to Bethlehem to anoint a new king—David (1 Samuel 16:1–13). Though David was God's chosen and the Spirit of the Lord was with him, David would not assume the throne for at least ten more years. At this point in David's journey, he is apparently under the age of twenty. He is both a shepherd for his father and an armor-bearer and musician for King Saul (1 Samuel 16:14–23).Jesse sent David to the field of battle to bring provisions to his brothers and their division. He also wanted a report back from his three oldest boys to see how they fared (1 Samuel 17:17–18). Here, David obeys his father and carries out his directive. It may have been about ten to fifteen miles—sixteen to twenty-four kilometers—from Jesse's home in Bethlehem to the Israelite camp. David arrives just as the army of the Israelites was forming up their battle line across the valley from the Philistines, who are doing the same. Armies would shout war cries to raise their spirits and intimidate the enemy.
