Parallel
Exodus 15:23
Berean Standard Bible · Westminster Leningrad Codex
And when they came to Marah (note: Marah means bitter.), they could not drink the water there because it was bitter. (That is why it was named Marah.)
וַיָּבֹ֣אוּ מָרָ֔תָה וְלֹ֣א יָֽכְל֗וּ לִשְׁתֹּ֥ת מַ֙יִם֙ מִמָּרָ֔ה כִּ֥י מָרִ֖ים הֵ֑ם עַל־ כֵּ֥ן קָרָֽא־ שְׁמָ֖הּ מָרָֽה׃
