(NIV1984) 1 Kings 18:31-35 – “Elijah took twelve stones, one for each of the tribes descended from Jacob, to whom the word of the LORD had come, saying, ‘Your name shale be Israel.’ With the stones he built an altar in the name of the LORD, and he dug a trench around it large enough to hold two seahs of seed. He arranged the wood, cut the bull into pieces and laid it on the wood. Then he said to them, ‘Fill four large jars with water and pour it on the offering and on the wood.’
“‘Do it again,’ he said, and they did it again.
“‘Do it a third time,’ he ordered, and they did it a third time. The water ran down around the altar and even filled the trench.”
Two seahs is probably about 13 quarts or 15 liters. That’s a huge trench! And therefore a TON of water! Not literally, but you know what I mean.
The twelve stone is significant because of what was said – one for each tribe. I don’t think this is the first time an altar of twelve stones has been made for this reason, but I’d have to do research into that.
How long did it take to dig that trench? And did he do all of this alone? How long did this take? And all the while the prophets of Baal are still bleeding and calling on Baal. Did any one of those 450 prophets stop and look at Elijah to see what he was doing? Did any of them watch him in fear? Did any of them stop to think what they were doing was wrong?
