John Gill Commentary Acts 8:4

"They therefore that were scattered abroad, went about preaching the word." — Acts 8:4 (ASV)

Therefore they that were scattered abroad By reason of the persecution in Jerusalem: the seventy disciples, and other ministers of the word; or the hundred and twenty, excepting the apostles,

went every where ; or went through the countries of Judea and Samaria, as far as Phenice, Cyrus, and Antioch:

preaching the word ; the Vulgate Latin, Syriac, and Ethiopic versions add, "of God", and so some copies; the Gospel, which is the word of God, and not man; which was not of men, nor received from men, but came from God, and by the revelation of Christ; and which was good news and glad tidings, of peace, pardon, righteousness and salvation, by Jesus Christ.
