20 And Miryam the prophetess, the sister of Aharon, took the timbrel in her hand. And all the women went out after her with timbrels and with dances.
21 And Miryam answered them, “Sing to יהוה, for He is highly exalted! The horse and its rider He has thrown into the sea!”
22 And Mosheh brought Yisra’ĕl from the Sea of Reeds, and they went out into the Wilderness of Shur. And they went three days in the wilderness and found no water.
23 And they came to Marah, and they were unable to drink the waters of Marah, for they were bitter. So the name of it was called Marah.
24 And the people grumbled against Mosheh, saying, “What are we to drink?”
25 Then he cried out to יהוה, and יהוה showed him a tree. And when he threw it into the waters, the waters were made sweet. There He made a law and a right-ruling for them, and there He tried them.
26 And He said, “If you diligently obey the voice of יהוה your Elohim and do what is right in His eyes, and shall listen to His commands and shall guard all His laws, I shall bring on you none of the diseases I brought on the Mitsrites, for I am יהוה who heals you.”
