Abraham and Moses were the mighty Prophets. None of the past prophets since Israel were as mighty as Moses:
Deuteronomy 34:10 "And there arose NOT a prophet since in Israel LIKE unto Moses.
Hence it does not make comparison of another mighty prophet Abraham with moses since Abraham came before Israel.
Then the Torah contains a prophecy of a future Prophet who will be like Moses and similar in mightiness:
God Almighty speaks to Moses in Book of Deuteronomy chapter 18 verse 18: "I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him."
:Book of Deuteronomy --18:20 “But if any prophet presumes to speak anything in my name that I have not authorized him to speak, or speaks in the name of other gods, that prophet must die
I found those who follow this scriptures take a different view of this here
in fulfillment of following Quranic verse:
"Those unto whom We gave the Scripture recognize him (Muhammad) as they recognize their sons. But verily, a party of them conceal the truth while [well] they know it"(2:146)
"Those who follow the Messenger, the unlettered Prophet, whom they find mentioned in their own (scriptures) in the law and the Gospel".(7:157)
How can we identify such a Prophet from their scriptures, how are they interpreting it wrongly?
