Psalms 29:4

The voice of the Lord [is] powerful
Or "with power" ^F1; as thunder, in the effect of it, shows; and so is the Gospel, when it comes, not in word only, but is attended with the power of God to the conversion and salvation of souls; it is then quick and powerful, ( Hebrews 4:12 ) ; and the word of Christ personal, when here on earth, was with power, ( Luke 4:32 ) ;

the voice of the Lord [is] full of majesty;
Christ, in his state of humiliation, spake and taught as one having authority; and now, in the ministration of his Gospel by his servants, he goes forth with glory and majesty, ( Psalms 45:3 Psalms 45:4 ) .
