Psalms 50:8

“Nevertheless, he saved them for his name’s sake, etc.] Not for any worth or worthiness in them; not for their righteousness sake, for they were a rebellious and disobedient people; but for his name’s sake, because his name was called upon them, and he was called the God of the Hebrews, as Aben Ezra observes; and the God of Abraham, Isaac, and Jacob, their ancestors; to whom he had promised the land of Canaan, and was their covenant God; and because of his covenant, and of his divine perfections, and the glory of them, which were engaged to make it good; therefore he saved them, (see <262009>Ezekiel 20:9,14).

“However scrupulous in external worship, it was offered as if they conferred an obligation in giving God His own, and with a degrading view of Him as needing it [Psa 50:9-13].

“I will not reprove thee for thy sacrifices or thy burnt-offerings - On the words “sacrifices” and “burnt-offerings” here used, see the notes at Isaiah 1:11. The meaning is, “I do not reprove or rebuke you in respect to the withholding of sacrifices. I do not charge you with neglecting the offering of such sacrifices. I do not accuse the nation of indifference in regard to the external rites or duties of religion. It is not on this ground that you are to be blamed or condemned, for that duty is outwardly and publicly performed. I do not say that such offerings are wrong; I do not say that there has been any failure in the external duties of worship. The charge - the reproof - relates to other…”

“I will not - This is not the principal matter of my charge, that thou hast neglected sacrifices which thou shouldst have offered. Psalms 50:9”
