George Haydock's Catholic Commentary
Psalms 17:32
Our God. Will any one then hinder Him from doing as He has said? (Haydock) --- Hebrew, "Who is the rock but our God?" (Berthier) --- God is often styled a rock, tsur. Yet St. Jerome and Pagnin render it "strong," or "the strong one." (Haydock) --- There is only one Lord and Saviour of all. (Worthington)
