Exodus 15:24-26

Lexham English Bible

²⁴ And the people grumbled against Moses, saying, “What shall we drink?” ²⁵ And he cried out to Yahweh, and Yahweh showed him a piece of wood, and he threw it into the water, and the water became sweet. There he made a rule and regulation for them, and there he tested them. ²⁶ And he said, “If you carefully listen to the voice of Yahweh your God and you do what is right in his eyes and give heed to his commands and you keep all his rules, then I will not bring about on you any of the diseases^[a] that I brought about on Egypt, because I am Yahweh your healer.
