Exodus 15:23-25

World English Bible

²³ When they came to Marah, they couldn’t drink from the waters of Marah, for they were bitter. Therefore its name was called Marah.^{[a] 24} The people murmured against Moses, saying, “What shall we drink?” ²⁵ Then he cried to Yahweh. Yahweh showed him a tree, and he threw it into the waters, and the waters were made sweet. There he made a statute and an ordinance for them, and there he tested them.
