Naphtuhim - a Hamitic tribe descended from Mizraim (Gen. 10:13). Others identify this word with Napata, the name of the city and territory on the southern frontier of Mizraim, the modern Meroe, at the great bend of the Nile at Soudan. This city was the royal residence, it is said, of Queen Candace (Acts 8:27). Here there are extensive and splendid ruins.
