 The Lord thy God will raise up to thee a PROPHET of thy nation and of thy brethren like unto me: him thou shalt hear:
 As thou desiredst of the Lord thy God in Horeb, when the assembly was gathered together, and saidst: Let me not hear any more the voice of the Lord my God, neither let me see any more this exceeding great fire, lest I die.  And the Lord said to me: They have spoken all things well.  I will raise them up a prophet out of the midst of their brethren like to thee: and I will put my words in his mouth, and he shall speak to them all that I shall command him.  And he that will not hear his words, which he shall speak in my name, I will be the revenger.

A Prophet will I raise up to them of their brethren, like you. Deuteronomy 18:18 Like, namely, as to the form of the flesh, but not in the eminence of His majesty. Accordingly we find the Lord Jesus called a Prophet. Hence this woman is now not far wrong.
