1 Samuel 14:12

8Then said Jonathan, Behold, we will pass over unto these men, and we will discover ourselves unto them.

9If they say thus unto us, Tarry until we come to you; then we will stand still in our place, and will not go up unto them.

10But if they say thus, Come up unto us; then we will go up: for the Lord hath delivered them into our hand: and this shall be a sign unto us.

11And both of them discovered themselves unto the garrison of the Philistines: and the Philistines said, Behold, the Hebrews come forth out of the holes where they had hid themselves.

12And the men of the garrison answered Jonathan and his armourbearer, and said, Come up to us, and we will shew you a thing. And Jonathan said unto his armourbearer, Come up after me: for the Lord hath delivered them into the hand of Israel.

13And Jonathan climbed up upon his hands and upon his feet, and his armourbearer after him: and they fell before Jonathan; and his armourbearer slew after him.

14And that first slaughter, which Jonathan and his armourbearer made, was about twenty men, within as it were an half acre of land, which a yoke of oxen might plow.

15And there was trembling in the host, in the field, and among all the people: the garrison, and the spoilers, they also trembled, and the earth quaked: so it was a very great trembling.

16And the watchmen of Saul in Gibeah of Benjamin looked; and, behold, the multitude melted away, and they went on beating down one another.
