My meditation; or, my speech, or discourse; my praising of God, mentioned Psa_104:33. Of him; concerning the glory of his works.
Shall be sweet; either,
1. To God; he will graciously accept it; praise being his most acceptable sacrifice, as is affirmed, Psa_69:30,31. Or rather,
2. To myself, as may be gathered from the next clause. He implies that he shall not only do this work, which a man may do unwillingly, or by constraint, but that he will do it cheerfully, and with delight; which is most pleasing to God.
I will be glad in the Lord; I will rejoice in the contemplation of God’s works, and in praising him for them.
