Testament of Solomon, F. C. Conybeare translation (1898):
So I said to him: "Bring to me thy child, who is, as thou sayest, in the Red Sea." But he said to me: "I will not bring him to thee. But there shall come to me another demon called Ephippas. Him will I bind, and he will bring him up from the deep unto me." And I said to him: "How comes thy son to be in the depth of the sea, and what is his name? "And he answered me: "Ask me not, for thou canst not learn from me. However, he will come to thee by any command, and will tell thee openly."
