29:6 Shall reduce them to pieces, etc: In Hebrew, shall make them to skip like a calf. The psalmist here describes the effects of thunder (which he calls the voice of the Lord) which sometimes breaks down the tallest and strongest trees; and makes their broken branches skip, etc. All this is to be understood mystically of the powerful voice of God's word in his church; which has broken the pride of the great ones of this world, and brought many of them meekly and joyfully to submit their necks to the sweet yoke of Christ.
