Exodus 15:15-25

15 then the chiefs of Edom are dismayed; trepidation seizes the heads of Mo'av; all those living in Kena'an are melted away.
16 Terror and dread fall on them; by the might of your arm they are still as stone until your people pass over, ADONAI, till the people you purchased pass over.
17 You will bring them in and plant them on the mountain which is your heritage, the place, ADONAI, that you made your abode, the sanctuary, Adonai, which your hands established.
18 ADONAI will reign forever and ever.
19 For the horses of Pharaoh went with his chariots and with his cavalry into the sea, but ADONAI brought the sea waters back upon them, while the people of Isra'el walked on dry land in the midst of the sea!"
20 Also Miryam the prophet, sister of Aharon, took a tambourine in her hand; and all the women went out after her with tambourines, dancing,
21 as Miryam sang to them: "Sing to ADONAI, for he is highly exalted! The horse and its rider he threw in the sea!"
22 Moshe led Isra'el onward from the Sea of Suf. They went out into the Shur Desert; but after traveling three days in the desert, they had found no water.
23 They arrived at Marah but couldn't drink the water there, because it was bitter. This is why they called it Marah [bitterness].
24 The people grumbled against Moshe and asked, "What are we to drink?"
25 Moshe cried to ADONAI; and ADONAI showed him a certain piece of wood, which, when he threw it into the water, made the water taste good. There ADONAI made laws and rules of life for them, and there he tested them.
