1 Samuel 14:11-14

11When both of them revealed themselves to the garrison of the Philistines, the Philistines said, “Behold, 1Hebrews are coming out of the holes where they have hidden themselves.”

12So the men of the garrison 2hailed Jonathan and his armor bearer and said, “Come up to us and 3we will tell you something.” And Jonathan said to his armor bearer, “Come up after me, for 4the Lord has given them into the hands of Israel.”

13Then Jonathan climbed up on his hands and feet, with his armor bearer behind him; and they fell before Jonathan, and his armor bearer put some to death after him.

14That first slaughter which Jonathan and his armor bearer made was about twenty men within about half a furrow in an acre of land.
