George Haydock's Catholic Commentary
Psalms 67:16
The mountain of God. The Church, which (Isaias ii. 2.) is called, The mountain of the house of the Lord upon the top of the mountains. It is here called a fat and a curdled mountain; that is to say, most fruitful, and enriched by the spiritual gifts and graces of the Holy Ghost. (Challoner) --- Fat. Hebrew, " as the hill of Basha," (Protestants) which was very fertile: the very name signifying "fat." (St. Jerome) (Haydock) --- The psalmist apostrophizes the mountains of Chanaan, which were very high, and those of Basan, where Og ruled; (Calmet) or he insinuates, that the latter could not vie with Sion, where the ark was now to be placed. (Berthier)
