George Haydock's Catholic Commentary
Psalms 118:139
My. Septuagint, "thy zeal." The just are animated with the zeal of God, like St. Paul. The enemies here mentioned were the Israelites, who attacked David, and not the Babylonians, who never knew God's law, or apostate captives, since we do not find that they attempted to injure Daniel, &c. (Berthier) --- Many, however, both at Ninive and Babylon prevaricated, Tobias i. 12. (Calmet)
