Commentaries:
Adam Clarke
Therefore my heart is glad - Unutterably happy in God; always full of the Divine presence; because whatsoever I do pleaseth him. The man Christ Jesus must be constantly in communion with God, because he was without spot and blemish.
My glory rejoiceth - My tongue, so called by the Hebrews, (see Psalms 57:8; Psalms 30:12), because it was bestowed on us to glorify God, and because it is our glory, being the instrument of expressing our thoughts by words. See Dodd. But soul bids as fair to be the meaning. See the notes on Acts 2:25, etc.
My flesh also shall rest in hope - There is no sense in which these and the following words can be spoken of David. Jesus, even on the cross, and breathing out his soul with his life, saw that his rest in the grave would be very short: just a sufficiency of time to Proverbs the reality of his death, but not long enough to produce corruption; and this is well argued by St. Peter, Acts 2:31.
