“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.”

“They that were scattered - went every where preaching - Thus the very means devised by Satan to destroy the Church became the very instruments of its diffusion and establishment. What are counsel, or might, or cunning, or rage, or malice, against the Lord, whether they are excited by men or devils!”

A.D.
1871
“they that were scattered abroad went everywhere preaching--Though solemnly enjoined to do this (Luk 24:47; Act 1:8), they would probably have lingered at Jerusalem, but for this besom of persecution which swept them out. How often has the rage of Christ's enemies thus "turned out rather unto the furtherance of the Gospel" (see Phi 1:12-13).”

The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
