Verse 21. My mouth shall speak the praise of the LORD. Whatever others may do, I will not be silent in the praise of the Lord: whatever others may speak upon, my topic is fixed once for all: I will speak the praise of Jehovah. I am doing it, and I will do it as long as I breathe. And let all flesh bless his holy name for ever and ever. Praise is no monopoly for one, even though he be a David; others are debtors, let them also be songsters. All men of every race, condition, or generation should unite to glorify God. No man need think that he will be rejected when he comes with his personal note of praise; all are permitted, invited, and exhorted to magnify the Lord. Specially should his holiness be adored: this is the crown, and in a certain sense the sum, of all his attributes. Only holy hearts will praise the holy name, or character of the Lord; oh, that all flesh were sanctified, then would the sanctity of God be the delight of all. Once let the song begin and there will be no end to it. It shall go on for ever and a clay, as the old folks used to say. If there were two forevers, or twenty forevers, they ought all to be spent in the praises of the ever living, ever blessing, ever blessed JEHOVAH. Blessed be the Lord for ever for having revealed to us his name, and blessed be that name as he has revealed it; yea, blessed be he above all that we can know, or think, or say. Our hearts revel in the delight of praising him. Our mouth, our mind, our lip, our life shall be our Lord's throughout this mortal existence, and when time shall be no more.
HINTS FOR PASTORS AND LAYPERSONS
Verse 21. Individual praise suggests the desire for universal praise. We like company in a good deed; we perceive the inadequacy of our own song; we desire others to be happy; we long to see that done which is right and good.
