David was thirsty and said, "How I wish someone would give me some water to drink from the cistern in Bethlehem near the gate!"

So the three elite warriors broke through the Philistine forces and drew some water from the cistern in Bethlehem near the gate. They carried it back to David, but he refused to drink it. He poured it out as a drink offering to the Lord

Benaiah son of Jehoida was a brave warrior from Kabzeel who performed great exploits. He struck down the two sons of Ariel of Moab. He also went down and killed a lion in a cistern on a snowy day.
