From the early Church Fathers to now.
“Solomon also spoke three thousand parables: and his poems were a thousand and five.”
“Of his three thousand proverbs a single book is left, while all the others perished during the captivity. And of his one thousand and five songs we still possess a single one, that is the Song of Songs.”
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.
