1st Samuel 14:34

31 That day they overcame the Philistines from Michmash to Aijalon: and the people were feeble from need of food.

32 And rushing at the goods taken in the fight, the people took oxen and sheep and young oxen, and put them to death there on the earth, and had a meal, taking the flesh with the blood in it.

33 Then it was said to Saul, See, the people are sinning against the Lord, taking the blood with the flesh. And he said to those who gave him the news, Now let a great stone be rolled to me here.

34 And Saul said, Go about among the people and say to them, Let every man come here to me with his ox and his sheep, and put them to death here, and take his meal: do no sin against the Lord by taking the blood with the flesh. So all the people took their oxen with them that night and put them to death there.

35 And Saul put up an altar to the Lord: this was the first altar which he put up to the Lord.

36 And Saul said, Let us go down after the Philistines by night, attacking them till the morning, till there is not a man of them living. And they said, Do whatever seems right to you. Then the priest said, Let us come near to God.

37 And Saul, desiring directions from God, said, Am I to go down after the Philistines? will you give them up into the hands of Israel? But he gave him no answer that day.
