1 Samuel 14:13-15

13And Jonathan climbed up upon his hands and upon his feet, and his armour-bearer after him; and they fell before Jonathan; and his armour-bearer slew after him.

14And that first slaughter which Jonathan and his armour-bearer wrought was about twenty men, as it were on the half-furrow of an acre of land.

15And there was trembling in the camp, in the field, and among all the people; the garrison, and the ravagers, they also trembled, and the earth quaked; for it was a trembling [from] 1God.
