The Lord is merciful and gracious - See the notes at Psalm 78:38. The idea here is derived evidently from Exodus 34:6-7 - that great and glorious statement of God himself in regard to his own character. Our world is a different world under that statement from what it would be if that and kindred declarations had not been made. There is here a "progression" of thought; an "advance" on the previous statements. At first the psalmist referred to his own individual experience Psalm 103:3-5; then he referred to the dealings of God toward the Hebrew people Psalm 103:6-7; and now he rises to the general contemplation of his character as it relates to all mankind. It was a characteristic of God in respect to all, that he was kind, compassionate, and forbearing.

Slow to anger - That is, patient; not soon excited; bearing much, and bearing it long. See James 5:11; compare Exodus 34:6-7.

And plenteous in mercy - Margin, "great of mercy." The Hebrew word means "much," or great;" and the idea is, that mercy is not manifested by him in small or stinted measure. It is rich; full; abundant; overflowing; free.

The Lord is merciful - See the note on Psalm 86:15.

The Lord is merciful and gracious,.... So he made himself known to Moses, Exodus 34:6, and so David found him to be, and therefore calls upon his soul to bless his name. God is "merciful" in the most tender and affectionate manner; he has bowels of mercy, which yearn towards his people, as those of a tender parent to its child, as the word signifies; his mercy is free, without any motive or merit in men to engage it; he delights in showing it; he constantly bestows it; it is the source of all good things; it is communicated through Christ; all mercies temporal and spiritual come by him; and this lays a foundation for faith and hope: and he is gracious, as appears in the eternal choice of his people to salvation; in providing a Saviour and a ransom for them; in giving all grace and the blessings of it to them in his Son; in giving him for them, and all things to them with him; in justifying them by his righteousness; in pardoning their sins for his sake; in taking them into his family; in regenerating, calling, preserving, and saving them:

slow to anger, or "longsuffering" (d); even to wicked men, to the vessels of wrath, to the old world, yea, to Jezebel, to whom he gave space to repent; which longsuffering being abused and despised, is an aggravation of condemnation: but rather here it intends God's longsuffering to his people, as before conversion, waiting till the time comes that he is gracious to them; and after conversion, notwithstanding their backslidings and revoltings; and this longsuffering is their salvation:

and plenteous in mercy; large and abundant in it, as appears by the various instances of it, and ways and methods in which he shows it; in election, in the covenant, in redemption, in regeneration, in pardon and eternal life; and by the abundance of it which he bestows on every one of his people; and by the vast numbers which do partake of it.

(d) "longanimis", V. L. Junius & Tremellius, Piscator, Cocceius.

The LORD is merciful and gracious, slow to anger, and plenteous in mercy.

plentious...: Heb. great in mercy

8-10. God's benevolence implies no merit. He shows it to sinners, who also are chastened for a time (Ex 34:6).

keep (anger)-in Le 19:18, bear a grudge (Jer 3:5, 12).

103:6-14 Truly God is good to all: he is in a special manner good to Israel. He has revealed himself and his grace to them. By his ways we may understand his precepts, the ways he requires us to walk in; and his promises and purposes. He always has been full of compassion. How unlike are those to God, who take every occasion to chide, and never know when to cease! What would become of us, if God should deal so with us? The Scripture says a great deal of the mercy of God, and we all have experienced it. The father pities his children that are weak in knowledge, and teaches them; pities them when they are froward, and bears with them; pities them when they are sick, and comforts them; pities them when they are fallen, and helps them to rise; pities them when they have offended, and, upon their submission, forgives them; pities them when wronged, and rights them: thus the Lord pities those that fear him. See why he pities. He considers the frailty of our bodies, and the folly of our souls, how little we can do, how little we can bear; in all which his compassion appears.
