6 Jonathan said to the young man who bore his armor, “Come, and let us go over to the garrison of these uncircumcised. It may be that Yahweh will work for us; for there is no restraint on Yahweh to save by many or by few.” 7 His armor bearer said to him, “Do all that is in your heart. Turn and, behold, I am with you according to your heart.” 8 Then Jonathan said, “Behold, we will pass over to the men, and we will reveal ourselves to them. 9 If they say thus to us, ‘Wait until we come to you!’ then we will stand still in our place, and will not go up to them. 10 But if they say this, ‘Come up to us!’ then we will go up; for Yahweh has delivered them into our hand. This shall be the sign to us.” 11 Both of them revealed themselves to the garrison of the Philistines: and the Philistines said, “Behold, the Hebrews are coming out of the holes where they had hidden themselves!” 12 The men of the garrison answered Jonathan and his armor bearer, and said, “Come up to us, and we will show you something!”
Jonathan said to his armor bearer, “Come up after me; for Yahweh has delivered them into the hand of Israel.” 13 Jonathan climbed up on his hands and on his feet, and his armor bearer after him: and they fell before Jonathan; and his armor bearer killed them after him. 14 That first slaughter, which Jonathan and his armor bearer made, was about twenty men, within as it were half a furrow’s length in an acre of land.

Commentary on 1 Samuel 14:1-15
(Read 1 Samuel 14:1-15)
Saul seems to have been quite at a loss, and unable to help himself. Those can never think themselves safe who see themselves out of God's protection. Now he sent for a priest and the ark. He hopes to make up matters with the Almighty by a partial reformation, as many do whose hearts are unhumbled and unchanged. Many love to have ministers who prophesy smooth things to them. Jonathan felt a Divine impulse and impression, putting him upon this bold adventure. God will direct the steps of those that acknowledge him in all their ways, and seek to him for direction, with full purpose of heart to follow his guidance. Sometimes we find most comfort in that which is least our own doing, and into which we have been led by the unexpected but well-observed turns of Divine providence. There was trembling in the host. It is called a trembling of God, signifying, not only a great trembling they could not resist, nor reason themselves out of, but that it came at once from the hand of God. He that made the heart, knows how to make it tremble.
