George Haydock's Catholic Commentary
Psalms 2:13
Trust for salvation through Christ, (Du Hamel) acting as he has directed, so that our hope may be well founded. (Menochius) --- This psalm is quoted six times in the New Testament, [Acts iv. 25., and xiii. 33., Hebrews i. 5., and v. 5., and Apocalypse ii. 27., and xix. 15.] which shews the concord of Scripture, and that the prophets saw the promises at a distance, following the law of love, which is as ancient as the world. (Berthier)
