1 Samuel 13:19-14:15
Now there was no smith to be found throughout all the land of Israel; for the Philistines said, "Lest the Hebrews make themselves swords or spears"; but every one of the Israelites went down to the Philistines to sharpen his plowshare, his mattock, his axe, or his sickle; and the charge was a pim for the plowshares and for the mattocks, and a third of a shekel for sharpening the axes and for setting the goads. So on the day of the battle there was neither sword nor spear found in the hand of any of the people with Saul and Jonathan; but Saul and Jonathan his son had them. And the garrison of the Philistines went out to the pass of Michmash.
One day Jonathan the son of Saul said to the young man who bore his armor, "Come, let us go over to the Philistine garrison on yonder side." But he did not tell his father. Saul was staying in the outskirts of Gib'e-ah under the pomegranate tree which is at Migron; the people who were with him were about six hundred men, and Ahi'jah the son of Ahi'tub, Ich'abod's brother, son of Phin'ehas, son of Eli, the priest of the LORD in Shiloh, wearing an ephod. And the people did not know that Jonathan had gone.
In the pass, by which Jonathan sought to go over to the Philistine garrison, there was a rocky crag on the one side and a rocky crag on the other side; the name of the one was Bozez, and the name of the other Seneh. The one crag rose on the north in front of Michmash, and the other on the south in front of Geba. And Jonathan said to the young man who bore his armor, "Come, let us go over to the garrison of these uncircumcised; it may be that the LORD will work for us; for nothing can hinder the LORD from saving by many or by few." And his armor-bearer said to him, "Do all that your mind inclines to; behold, I am with you, as is your mind so is mine."
Then said Jonathan, "Behold, we will cross over to the men, and we will show ourselves to them. If they say to us, 'Wait until we come to you,' then we will stand still in our place, and we will not go up to them. But if they say, 'Come up to us,' then we will go up; for the LORD has given them into our hand. And this shall be the sign to us."
So both of them showed themselves to the garrison of the Philistines; and the Philistines said, "Look, Hebrews are coming out of the holes where they have hid themselves." And the men of the garrison hailed Jonathan and his armor-bearer, and said, "Come up to us, and we will show you a thing." And Jonathan said to his armor-bearer, "Come up after me; for the LORD has given them into the hand of Israel." Then Jonathan climbed up on his hands and feet, and his armor-bearer after him. And they fell before Jonathan, and his armor-bearer killed them after him; and that first slaughter, which Jonathan and his armor-bearer made, was of about twenty men within as it were half a furrow's length in an acre of land. And there was a panic in the camp, in the field, and among all the people; the garrison and even the raiders trembled; the earth quaked; and it became a very great panic.
