Philo Judaeus De Migratione Abrahami 83

[83] Do you not see that conjurors and enchanters, who attempting to contend against the divine word with their sophistries, and who daring to endeavour to do other things of a similar kind, labour not so much to display their own knowledge, as to tear to pieces and turn into ridicule what was done? ¹ For they even transform their rods into the nature of serpents, and change water into the complexion of blood, and by their incantations they attract the remainder of the frogs to the land, and, like miserable men as they are, they increase everything for their own destruction, and while thinking to deceive others they are deceived themselves.
