1 Samuel 14:12 WEB

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

¹¹  Both of them disclosed themselves to the garrison of the Philistines: and the Philistines said, Behold, the Hebrews come forth out of the holes where they had hid themselves.

¹²  The men of the garrison answered Jonathan and his armor bearer, and said, Come up to us, and we will show you a thing. 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.
