25 And he cried unto the Lord; and the Lord showed him a tree, which when he had cast it into the waters, the waters were made sweet. There he gave them statutes and rights, 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 thy Healer.
27 And they came to Elim, where there were twelve fountains of water and seventy palm trees; and they encamped there by the waters.
