Exodus 15:25-27

American Standard Version

²⁵ An he cried unto Jehovah; and Jehovah showed him a tree, and he cast it into the waters, and the waters were made sweet. There he made for them a statute and an ordinance, and there he proved them; ²⁶ and he said, If thou wilt diligently hearken to the voice of Jehovah thy God, and wilt do that which is right in his eyes, and wilt give ear to his commandments, and keep all his statutes, I will put none of the diseases upon thee, which I have put upon the Egyptians: for I am Jehovah that healeth thee. ²⁷ And they came to Elim, where were twelve springs of water, and threescore and ten palm-trees: and they encamped there by the waters.
