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
