Jerome
Patristic
c. A.D. 347–420
“(Verse 23.) Behold, we come to you: for you are the Lord our God. Truly the hills were deceitful, and the multitude (or strength) of the mountains: truly in the Lord our God is the salvation of Israel. Let the penitent say this, forsaking all pride, and the multitude or height of the mountains and hills, by which he exalted himself against God, and being humbled, let him speak: Truly in the Lord our God is the salvation of Israel.”
