Melachim Bais 2:7-9

Orthodox Jewish Bible

⁷ And chamishim ish (fifty men) of the Bnei HaNevi’im went, standing opposite them at a distance; and they two stood by the Yarden.

⁸ And Eliyahu took his aderet (mantle, cloak), and rolled it up, and struck the mayim, and they were split from here and from there, so that they two crossed over on charavah (dry ground [See Yehoshua 3:17]).

⁹ And it came to pass, when they were crossed over, that Eliyahu said unto Elishah, Request what I shall do for thee, before I am taken away from thee. And Elishah said, Let, now, a double portion of thy ruach be upon me.
