Exodus 15:25-27

King James Version

²⁵ And he cried unto the Lord; and the Lord shewed him a tree, which when he had cast into the waters, the waters were made sweet: there he made for them a statute and an ordinance, and there he proved them,

²⁶ And said, If thou wilt diligently hearken to the voice of the Lord thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the Lord that healeth thee.

²⁷ And they came to Elim, where were twelve wells of water, and threescore and ten palm trees: and they encamped there by the waters.
