Jerome of Stridon
He will establish a covenant of peace with them, one that does not involve conflict or strife, for His presence is in the world (Ps. 55:3). This covenant embodies the peace of Christ, which surpasses all comprehension (Phil. 4), and declares, “My peace I give unto you, my peace I leave unto you” (John 14:27). I will eliminate the ferocious beasts from the earth—these are the vices and passions that torment human souls, as well as the sinister forces that launch assaults against them. Those who inhabit the wilderness shall find safety and rest among the forests. For the Lord will open the oak trees, and all will proclaim glory in His sanctuary (Psalm 28:9). When the ferocious beasts are banished and the land becomes a desolate place, they will lie down without fear of such creatures and will affirm, “The Lord is my light and my salvation; whom shall I fear?” (Psalm 26:1).
