When Saul saw the Philistine army, he was afraid and trembled violently.
Here is, I. The design of the Philistines against Israel. They resolved to fight them, Sa1 28:1. If the Israelites had not forsaken God, there would have been no Philistines remaining to molest them; if Saul had not forsaken him, they would by this time have been put out of all danger by them.
Commenting on 1 Samuel 28:1-6
And when Saul saw the host of the Philistines,.... From the mountains of Gilboa, where he had pitched his camp: he was afraid, and his heart greatly trembled; on sight of the numbers of them, and thinking perhaps of the death of Samuel, and of the loss of David; who was now among the Philistines, and might possibly fight against him, and for the Philistines...
When Saul saw - He saw from the superiority of his enemies, from the state of his army, and especially from his own state towards God, that he had every thing to fear.
