And when they came to Marah, they could not drink of the waters of Marah, for they were bitter: therefore the name of it was called Marah.

and they come in to Marah, and have not been able to drink the waters of Marah, for they `are' bitter; therefore hath `one' called its name Marah.

And when they came to Marah, they could not drink the water there because it was bitter. (That is why it was named Marah.)
