1 Samuel 14:33-35

33 Then they told Saul, saying, Behold, the people sin against the LORD, in that they eat with the blood. And he said, You have transgressed: roll a great stone to me this day.

34 And Saul said, Disperse yourselves among the people, and say to them, Bring me here 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 to the LORD: the same was the first altar that he built to the LORD.
