1 Samuel 14:34
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.
1 Samuel 14:34 belongs to the history of the choosing of Saul and the beginning of his reign, before the Lord's rejection of Saul and his family and the anointing of David. Its immediate setting was Saul's rash decree imposing a death sentence on anyone who ate that day, under which Jonathan, unaware of the decree, ate honey and was sentenced to death. The problem addressed was that the hungry Israelites hastily slaughtered the cattle they had taken and ate the meat with the blood, violating God's command.
In response Saul directed every man to bring his ox and his sheep and slay them properly with the blood separated, so as not to sin against the Lord in eating with the blood. He also ordered that an offering be made to the Lord as the Mosaic law required. The account shows Saul becoming rash, weak, and self-sufficient as he departed from God, and his rashness stands as a warning against speaking hastily.
