Acts 8:36

“And as they went on their way, etc.] In the road from Jerusalem to Gaza; Philip preaching, and the eunuch hearing, and conversing in a religious and spiritual way together; and Beza says in one exemplar it is added, “conferring one with another”; about the person and office of Christ, the doctrines of the Gospel, and the ordinances of it; as appears by what follows, both by the eunuch’s request to be admitted to baptism, and his confession of faith: they came unto a certain water; which some say was at Bethhoron, in the tribe of Judah or Benjamin; and others think it was the river Eleutherus; the former is more likely; concerning which Jerom f438 gives this account: “Bethzur in the tribe of…”
