Shemot 15:25-27

Orthodox Jewish Bible

²⁵ And he cried unto Hashem; and Hashem showed him an etz (tree) which when he had cast into the mayim, the waters were made sweet (i.e., potable, fit for drinking); at that place He made for them a chok (statute, requirement, obligation) and a mishpat (divine judgment), and there He tested them,

²⁶ And said, If thou wilt diligently pay heed to the voice of Hashem Eloheicha, and will do that which is yashar in His sight, and will give ear to do His mitzvot, and be shomer over all His chok, I will put none of these machalah (diseases) upon thee, which I put upon the Egyptians; for Ani Adonoi rofecha (I am Hashem that healeth thee). [2Kgs15:5;Amos 4:10]

²⁷ And they came to Elim (Great Trees). There were twelve springs of mayim, and threescore and ten date-palm trees; and they encamped there by the mayim.
