Who forgiveth all thine iniquities; who healeth all thy diseases;
Ver. 3. Who forgiveth all thine iniquities] David not only taketh upon him with a holy imperiousness, laying God's charge upon his soul to be thankful; but intending to show himself good cause why to be so, he worthily beginneth with remission of sin, as a complexive mercy, and such as comprehendeth all the rest. He had a crown of pure gold set upon his head, Psalms 21:3; but here he blesseth God for a better crown; Psalms 103:4, "Who crowneth thee with lovingkindness," &c. And how was this crown set on his head but by forgiving all his iniquities?
Who healeth all thy diseases] Corporal and spiritual. Quod sanitas in corpore id sanctitas in corde. Jehovah Rophe, or the Lord the physician (as he is called, Exo 15:26), cureth his people on both sides, maketh them whole every whit. See Isa 19:22 Matthew 8:17. He bore our diseases.
