1 Samuel 14:24-34 - Saul's Oath Leads To Trouble
24 Now the men of Israel were hard pressed that day, for Saul had made the army agree to this oath: "Cursed be the man who eats food before evening! I will get my vengeance on my enemies!" So no one in the army ate anything.
25 Now the whole army entered the forest and there was honey on the ground. 26 When the army entered the forest, they saw the honey flowing, but no one ate any of it, for the army was afraid of the oath. 27 But Jonathan had not heard about the oath his father had made the army take. He extended the end of his staff that was in his hand and dipped it in the honeycomb. When he ate it, his eyes gleamed. 28 Then someone from the army informed him, "Your father put the army under a strict oath saying, 'Cursed be the man who eats food today!' That is why the army is tired."
29 Then Jonathan said, "My father has caused trouble for the land. See how my eyes gleamed when I tasted just a little of this honey. 30 Certainly if the army had eaten some of the enemies' provisions that they came across today, would not the slaughter of the Philistines have been even greater?"
31 On that day the army struck down the Philistines from Micmash to Aijalon, and they became very tired. 32 So the army rushed greedily on the plunder, confiscating sheep, cattle, and calves. They slaughtered them right on the ground, and the army ate them blood and all. 33 Now it was reported to Saul, "Look, the army is sinning against the Lord by eating even the blood." He said, "All of you have broken the covenant! Roll a large stone over here to me." 34 Then Saul said, "Scatter out among the army and say to them, 'Each of you bring to me your ox and sheep and slaughter them in this spot and eat. But don't sin against the Lord by eating the blood." So that night each one brought his ox and slaughtered it there.
