David is still on the run from king Saul. They were hiding in the forest of Hereth which is in Judah, and the Philistines were attacking the city of Keilah. David asked the Lord if they were to go there and help, and the answer was "Yes!" This scared his men since they were in Judah and could be easily captured, so David asked again, and the answer was yes. They went and defeated the Philistines, but Saul heard about it and came after them. David asked if Saul was coming and the answer was yes. David asked if the people of the town would turn them over to Saul, and the answer was yes, so David and his men left. They went to Horesh, and Jonathan, Saul's son, came and encouraged David that he would be king someday and that Jonathan would be his right hand man. They made a covenant and Jonathan left. The Ziphites had spied David living among them, so they informed king Saul. He came after David, and almost got them, but then word came that the Philistines were raiding the land, so Saul went home to fight the Philistines, and David and his men went to En Gedi.
Psalm 54 is a song that was written about this experience. It is an imprecatory Psalm, which means it is a song that cries out for justice against the enemy. It begins with a cry for help, and then it says, "Surely, god is my help!" The song ends with David praising the Lord who will help him triumph over his foes.
