George Haydock's Catholic Commentary
Psalms 48:16
Redeem. Chaldean and some Rabbins seem to understand this of purgatory. "He will draw me from hell, and give me a place in his habitation." (Genebrard) --- Others explain it of Christ's resurrection, or of the liberation of the patriarchs from limbo. (Cassiodorus) --- It seems a full solution of the enigma [in] ver. 6. I repent, and shall have nothing to fear. (Berthier)
