1 Samuel 14:31-35
King James Version
31 And they smote the Philistines that day from Michmash to Aijalon: and the people were very faint.
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.
33 Then they told Saul, saying, Behold, the people sin against the Lord, in that they eat with the blood. And he said, Ye have transgressed: roll a great stone unto me this day.
34 And Saul said, Disperse yourselves among the people, and say unto them, Bring me hither every man his ox, and every man his sheep, and slay them here, and eat; and sin not against the Lord in eating with the blood. And all the people brought every man his ox with him that night, and slew them there.
35 And Saul built an altar unto the Lord: the same was the first altar that he built unto the Lord.Read full chapter
