1 Samuel 14:11-15

11So they both let themselves be seen by the Philistine garrison. “Look, some Hebrews are coming out of the holes where they were hiding,” the Philistines said.

12So the men of the garrison shouted down to Jonathan and his armor-bearer saying, “Come up to us and we’ll teach you a lesson!” Then Jonathan said to his armor-bearer, “Follow me, for Adonai has handed them over to Israel!”

13So Jonathan climbed up on his hands and feet, with his armor-bearer behind him. Then they fell before Jonathan, his armor-bearer behind him finishing them off.

14That first assault that Jonathan and his armor-bearer made struck down about 20 men within about half a furrow in an acre of land.

15Terror then spread through the camp, in the field, and among all the troops. Even the outposts and the raiders also trembled, when the earth quaked—it was a trembling from God.
