Luke 9:19

They answering said, John the Baptist
This was the opinion of some who thought that he was risen from the dead, as in ( Luke 9:7 ) .

but some say Elias;
the prophet, and the Tishbite; who according to the Jewish notion, was to be the forerunner of the Messiah, so in ( Luke 7:8 ) .

and others say: that one of the old prophets is risen again;
thus were they divided in their sentiments about him. (See Gill on Luke 9:8)
