From the early Church Fathers to now.
“And the children of Israel offended the Lord their God with things that were not right: and built them high places in all their cities from the tower of the watchmen to the fenced city.”
“With the words "from watchtower to fortified city" [the Scripture] denounces the large number of their idols, that is, [there were] idols from border to border. The text refers to the "fortified city" as Jerusalem, but other [interpreters] say Antioch.”
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.
