Exodus 15:25

And Moses cried to the Lord, and the Lord showed him a tree, and he cast it into the water, and the water was sweetened: there he established to him ordinances and judgments, and there he proved him,

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,

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.
