George Haydock's Catholic Commentary
Psalms 118:127
Topaz. Hebrew paz, which denotes "the purest gold" of Phison, Genesis ii. 11. (Calmet) --- The topaz was discovered only in the reign of Ptolemy, father of Philadelphus. (St. Hilary) (Pliny, [Natural History?] xxvii. 8.) --- Yet St. Jerome and others have the topaz, (Berthier) which St. Ambrose represents as the finest of precious stones. (Calmet) --- The more the law is despised by the wicked, the more are the just in love with it. (Worthington)
