George Haydock's Catholic Commentary
Psalms 110:10
Fear. Hebrew, "is the chief part of wisdom." (Jansenius) --- This fear intimates the virtue of religion, to which the Israelites gave the preference over prudence, &c. (Josephus, contra App. 2.) --- This distinguished them from other nations, Deuteronomy iv. 8. (Calmet) --- Fear is the beginning, charity the end of wisdom. (Eusebius) --- Beginning with fear, we ascend to true wisdom, which are the first and last of the gifts of the Holy Ghost. (Worthington) --- Do it. Act conformably to this fear. (Haydock) --- Speculative wisdom is good, but not sufficient, Romans xi. 13. (St. Chrysostom, &c.) --- Many read ea, "those things," with the Hebrew, while the Septuagint have eam, this wisdom. But Houbigant adheres to the Vulgate. (Berthier) --- His. God's, (St. Chrysostom) though some would refer ejus to intellectus. (Berthier) --- He shall be praised for ever who has been so well informed as to adopt the fear or wisdom of the Lord for his guide. (Haydock)
