1 Samuel 15:22 Douay-Rheims

And Samuel said: Doth the Lord desire holocausts and victims, and not rather that the voice of the Lord should be obeyed? For obedience is better than sacrifices: and to hearken rather than to offer the fat of rams.

“Moreover, the prophets indicate in the fullest manner that God stood in no need of their slavish obedience, but that it was upon their own account that He enjoined certain observances in the law. And again, that God needed not their oblation, but [merely demanded it], on account of man himself who offers it, the Lord taught distinctly, as I have pointed out. For when He perceived them neglecting righteousness, and abstaining from the love of God, and imagining that God was to be propitiated by sacrifices and the other typical observances, Samuel did even thus speak to them: "God does not desire whole burnt-offerings and sacrifices, but He will have His voice to be hearkened to. Behold, a ready obedience is better than sacrifice, and to hearken than the fat of rams."”

“Samuel, that great man, no less clearly reproved Saul, saying, "Is not the word better than a gift?" For hereby one fulfills the law and pleases God, as he says, "The sacrifice of praise shall glorify me." Let one "learn what this means, I will have mercy, and not sacrifice," and I will not condemn the adversaries.”

“Behold, obeying His command is better than a choice offering. To hearken [is better] than the fat of rams. This refers to, "Behold, obeying [is better] than a choice offering, and to hearken [is better] than the fat of rams."”

“And Samuel said,.... In reply to Saul: hath the Lord as great delight in burnt offerings and sacrifices, as in obeying the voice of the Lord? no, certainly, the one being merely ceremonial, the other moral; the one supposes sin committed, for which sacrifice is offered; the other moral, and is a compliance with the will of God, and is neither sinful, nor supposes anything sinful, and therefore must be the more acceptable: behold, to obey is better than sacrifice, and to hearken than the fat of rams; which always was claimed by the Lord as his right and due; or the fattest rams or best sacrifices, of whatever sort, whether burnt offerings, or sin offerings, or peace offerings; for had man obeyed the will of God, and not sinned, there would have been no need of sacrifice; and that was only acceptable to God when offered with a heart truly sensible of sin, and penitent for it, and in the faith of the great sacrifice of Christ, of which all sacrifices under the law were typical, and led unto.”

“Hath the Lord as great delight, etc. - This was a very proper answer to, and refutation of Saul's excuse. Is not obedience to the will of God the end of all religion, of its rites, ceremonies, and sacrifices?”

“Without entering, therefore, into any discussion of the meaning of the ban, as Saul only wanted to cover over his own wrong-doings by giving this turn to the affair, Samuel put a stop to any further excuses, by saying, "Hath Jehovah delight in burnt-offerings and slain-offerings as in hearkening to the voice of Jehovah? (i.e., in obedience to His word.) Behold, hearing (obeying) is better than slain-offerings, attending better than fat of rams." By saying this, Samuel did not reject sacrifices as worthless; he did not say that God took no pleasure in burnt-offerings and slain-offerings, but simply compared sacrifice with obedience to the command of God, and pronounced the latter of greater worth than the former. "It was as much as to say that the sum and substance of divine worship consisted in obedience, with which it should always begin, and that sacrifices were, so to speak, simple appendices, the force and worth of which were not so great as of obedience to the precepts of God" (Calvin). But it necessarily follows that sacrifices without obedience to the commandments of God are utterly worthless; in fact, are displeasing to God, as Psa 50:8., Isa 1:11., Isa 66:3, Jer 6:20, and all the prophets, distinctly affirm. There was no necessity, however, to carry out this truth any further. To tear off the cloak of hypocrisy, with which Saul hoped to cover his disobedience, it was quite enough to affirm that God's first demand was obedience, and that observing His word was better than sacrifice; because, as the Berleb. Bible puts it, "in sacrifices a man offers only the strange flesh of irrational animals, whereas in obedience he offers his own will, which is rational or spiritual worship" (Rom 12:8). This spiritual worship was shadowed forth in the sacrificial worship of the Old Testament. In the sacrificial animal the Israelite was to give up and sanctify his own person and life to the Lord. (For an examination of the meaning of the different sacrifices, see Pent. pp. 505ff., and Keil's Bibl Archol. 41ff.) But if this were the design of the sacrifices, it was clear enough that God did not desire the animal sacrifice in itself, but first and chiefly obedience to His own word. In Sa1 15:22, טּוב is not to be connected as an adjective with זבח, "more than good sacrifice," as the Sept. and Thenius render it; it is rather to be taken as a predicate, "better than slain-offerings," and מזּבח is placed first simply for the sake of emphasis. Any contrast between good and bad sacrifices, such as the former construction would introduce into the words, is not only foreign to the context, but also opposed to the parallelism. For אילים חלב does not mean fat rams, but the fat of rams; the fat portions taken from the ram, which were placed upon the altar in the case of the slain-offerings, and for which חלב is the technical expression (compare Lev 3:9, Lev 3:16, with Lev 3:4, Lev 3:11, etc.). "For," continued Samuel (Sa1 15:23), "rebellion is the sin of soothsaying, and opposition is heathenism and idolatry." מרי and הפצר are the subjects, and synonymous in their meaning. קסם חטּאת, the sin of soothsaying, i.e., of divination in connection with the worship of idolatrous and demoniacal powers. In the second clause idols are mentioned instead of idolatry, and compared to resistance, but without any particle of comparison. Opposition is keeping idols and teraphim, i.e., it is like worshipping idols and teraphim. און, nothingness, then an idol or image (vid., Isa 66:3; Hos 4:15; Hos 10:5, Hos 10:8). On the teraphim as domestic and oracular deities, see at Gen 31:19. Opposition to God is compared by Samuel to soothsaying and oracles, because idolatry was manifested in both of them. All conscious disobedience is actually idolatry, because it makes self-will, the human I, into a god. So that all manifest opposition to the word and commandment of God is, like idolatry, a rejection of the true God. "Because thou hast rejected the word of Jehovah, He hath rejected thee, that thou mayst be no longer king." ממּלך = מלך מהיוה (Sa1 15:26), away from being king.”
