1 Samuel 14:32
And the people flew upon the spoil, and took sheep, and oxen, and calves, and slew them on the ground: and the people did eat them with the blood. And the people flew upon the spoil, and took sheep, and oxen, and calves, and slew them on the ground: and the people did eat them with the blood.
The verse belongs to the crisis in which God rebuked Saul's perversity for his presumptuous offering and withheld from him the honor of defeating the Philistines, choosing instead Jonathan, a man who feared the Lord and acted from divine impulse, to deliver Israel through a secret attack with his faithful, praying armor-bearer in faith that the Lord saves by many or by few, confirmed by prayer and an agreed sign. Saul's rash vow and ban kept the people from eating. The vow barred anyone from eating until the evening and showed great lack of wisdom in zeal. It was a hard and demanding day of labor for the people.
The people were left faint and suffered much from faintness. When the restriction ended, they rushed upon the captured spoil animals. When the vow's time expired they were so faint that they violated God's command. They slaughtered sheep, oxen, and calves on the ground and ate the meat with the blood, thereby breaking God's law and command that forbade eating blood.
