Exodus 15:22

They journeyed from before Hahiroth and passed through the midst of the sea into the wilderness; and they went three days’ journey in the wilderness of Etham and camped at Marah.

So Saul struck the Amalekites, from Havilah as you go to Shur, which is east of Egypt.

Now David and his men went up and raided the Geshurites and the Girzites and the Amalekites; for they were the inhabitants of the land from ancient times, as you come to Shur even as far as the land of Egypt.

But He led forth His own people like sheep And guided them in the wilderness like a flock;

To Him who led His people through the wilderness, For His lovingkindness endures forever;

And they *sang the song of Moses, the slave of God, and the song of the Lamb, saying, “Great and marvelous are Your works, O Lord God, the Almighty; Righteous and true are Your ways, King of the nations!
