1 Kings 18:30-32

Young's Literal Translation

³⁰ And Elijah saith to all the people, `Come nigh unto me;' and all the people come nigh unto him, and he repaireth the altar of Jehovah that is broken down;

³¹ and Elijah taketh twelve stones, according to the number of the tribes of the sons of Jacob, unto whom the word of Jehovah was, saying, `Israel is thy name;'

³² and he buildeth with the stones an altar, in the name of Jehovah, and maketh a trench, as about the space of two measures of seed, round about the altar.
