From the early Church Fathers to now.
“And Achior being called for came, and Judith said to him: The God of Israel, to whom thou gavest testimony, that he revengeth himself of his enemies, he hath cut off the head of all the unbelievers this night by my hand.”
“And. This is related after ver. 5, in the following chapter, in Greek, Syriac, and the old Vulgate, (Calmet) and indeed it seems to be there in its proper place. — Head, or general. (Haydock)”
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.
