Mishnà su Esodo 5:2

A Galilean min said: I complain against you Pharisees, that you write the name of the ruler and the name of Moses together on a divorce document. The Pharisees said: we complain against you, Galilean min, that you write the name of the ruler together with the divine name on a single page [of Torah]? And furthermore that you write the name of the ruler above and the divine name below? As it is said, "And Pharoah said, Who is the Lord that I should hearken to his voice to let Israel go?" (Exodus 5:2) But when he was smitten what did he say? "The Lord is righteous" (Exodus 9:27).
