1 Samuel 14:33-34
33-34Saul was told, "Do something! The soldiers are sinning against God. They're eating meat with the blood still in it!"
Saul said, "You're biting the hand that feeds you! Roll a big rock over here—now!" He continued, "Disperse among the troops and tell them, 'Bring your oxen and sheep to me and butcher them properly here. Then you can feast to your heart's content. Please don't sin against God by eating meat with the blood still in it.'"
And so they did. That night each soldier, one after another, led his animal there to be butchered.
35That's the story behind Saul's building an altar to God. It's the first altar to God that he built.
