“Prayer. Greek, “adoration, that they might receive a blessing from the Most High.” (Haydock) — Power. In keeping Philopator out of the temple. God granted his request, (Calmet. litaneios ) “and scourged him who was so insolent and bold…throwing him like a reed, unable to move, and speechless on the pavement,” 2 Machabees ii. 26. After Philopator’s guards had removed him, the high priest congratulated the people, (ver. 26.) expressing his abhorrence of their enemies in general, though he only mentions three neighbouring nations which had shewn a particular enmity to the Jews, when a contrary behaviour might have been expected, ver. 28. (Haydock)”

“To show forth the power of God. That is, to preach his mercy, who gives us gladness of heart, and peace in eternal times, that all Israelite men, and lovers of the eternal King, may preach the might and the goodness of God in the deliverance of his people.”

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.
