Keluaran 15:23

Setibanya di Mara, mereka menemukan air, tetapi air di sana tidak bisa diminum karena pahit. Itulah sebabnya tempat itu dinamai ‘Mara’, yang artinya ‘pahit’.

¶ 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.
