Jdt 9:2 · Douay-Rheims
“O Lord God of my father Simeon, who gavest him a sword to execute vengeance against strangers, who had defiled by their uncleanness, and uncovered the virgin unto confusion:”
Post-Reformation c. 1650 – 1900

A.D.
George Leo Haydock Catholic
1774–1849
“Gavest him a sword, &c. The justice of God is here praised, in punishing by the sword of Simeon the crime of the Sichemites: and not the fact of Simeon, which was justly condemned by his father, Genesis xlix. 5. Though even with regard to this fact, we may distinguish between his zeal against the crime committed by the ravishers of his sister, which zeal may be considered just: and the manner of his punishing that crime, which was irregular and excessive. (Challoner) — The former is here commended. (Worthington) (Menochius) — Yet Simeon was not blameless. God put the sword into his hand as he makes use of tyrants; in which sense Nabuchodonosor is styled his servant, Jeremias xxv. 9., Ezechiel xxix. 18., and Genesis xxxiv. 2, 25.”

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.
