Melachim Alef 18:31-33

Orthodox Jewish Bible

³¹ And Eliyahu took twelve avanim (stones), according to the mispar (number) of the Shivtei Bnei Ya’akov, unto whom the Devar Hashem came, saying, Yisroel shall be Shemecha;

³² And with the avanim (stones) he built a Mizbe’ach in the Shem of Hashem; and he made a te’alah (trench) around the Mizbe’ach, as the space of two seahs of zera (seed).

³³ And he laid the wood in order, and cut up the bull, and laid it on the wood, and said, Fill four jugs with mayim, and pour it on the olah and on the wood.
