1 Samuel 2:3 Douay-Rheims

Do not multiply to speak lofty things, boasting: let old matters depart from your mouth: for the Lord is a God of all knowledge, and to him are thoughts prepared.

“No sensible person, then, will be proud of his wisdom … but will follow the excellent advice of blessed Hannah and of the prophet Jeremiah, "Let not the wise man glory in his wisdom and let not the strong man glory in his strength and let not the rich man glory in his riches." But what is true glory and what makes one great? "In this," says the prophet, "let him that glories, glory, that he understands and knows that I am the Lord." This constitutes the pinnacle of human dignity, this is his glory and greatness: truly to know what is great and to cleave to it, and to seek after glory from the Lord of glory.”

“Are these words going to be regarded as simply the words of one mere woman giving thanks for the birth of her son? Are people's minds so turned away from the light of truth that they do not feel that the words poured out by this woman transcend the limit of her own thoughts? Surely, anyone who is appropriately moved by the events whose fulfillment has already begun, even in this earthly pilgrimage, must listen to these words and observe and recognize that through this woman (whose very name, Hannah, means "God's grace"), there speaks, by the spirit of prophecy, the Christian religion itself, the City of God itself, whose king and founder is Christ. There speaks, in fact, the grace of God itself, from which the proud are estranged so that they fall, with which the humble are filled so that they rise up, which was in fact the chief theme that rang out in her hymn of praise. Now it may be that someone will be ready to say that the woman didn't utter a prophecy but merely praised God in an outburst of exultation for the son who was granted in answer to her prayer. If so, what is the meaning of this passage, "He has made weak the bow of the mighty ones, and the weak have girded themselves with strength. Those who were full of bread have been reduced to want, and the hungry have passed over the earth. Because the barren woman has given birth to seven, while she who has many children has become weak." Had Hannah herself really borne seven children, although she was barren? She had only one son when she spoke these words; and even afterwards she did not give birth to seven, or to six, which would have made Samuel the seventh. She had in fact three male and two female children. And then observe her concluding words, spoken among that people at a time when no one had yet been king over them: "He gives strength to our kings and will exalt the horn of his anointed." How is it that she said this, if she was not uttering a prophecy? Therefore, let the church of Christ speak, the "city of the great king," the church that is "full of grace," fruitful in children. Let it speak the words that it recognizes as spoken prophetically about itself, so long ago, by the lips of this devout mother, "My heart is strengthened in the Lord; my horn is exalted in my God." Her heart is truly strengthened and her horn truly exalted, because it is "in the Lord her God," not in herself, that she finds strength and exaltation.”

“Do not abound in speaking so very proudly. All those who are haughty when they experience good fortune. About Penina who behaved haughtily toward her, was she speaking, according to the simple explanation. However, according to the drash, we follow Targum Yonoson's rendition [that she is referring to Nevuchadnetzar]. Harshness. Strong speech. Others explain עָתָק as an expression of something which is removed [from the truth], as in "from there he moved [וַיַעְתֵּק] to the mountain." [The meaning here being "let not] falsehood come out of your mouth." For a God of knowledge is Adonoy. He knows what is in your hearts. And by Him all actions are counted. All people's deeds are counted before Him. Counted. An expression of number, as in, "and the number [וְתֹכֶן] of bricks shall you give."”

“Talk no more so exceeding proudly,.... At such an high rate, in such an overbearing manner, as if above everyone; this may have respect to Peninnah, and all that joined with her to provoke Hannah to anger, and make her fret, insulting and triumphing over her, because she had not children, as they had; but now their mouths would be stopped, and their talk over, and not give themselves the haughty airs they had done, at least there would be no occasion for them: let not arrogancy come out of your mouth; arrogating to themselves, and to their merits, what they enjoyed, as children, riches, &c. when all come from the Lord; or what is "hard" (i), intolerable, which bears so hard on those to whom it is said, that it cannot be bore with; or what is "old" (k), and trite, old sayings concerning barren women, as if of no use in the world, and disagreeable to God, and as having no share in his favour. The Targum renders the word by reproaches, or blasphemies: for the Lord is a God of knowledge; or knowledges (l): of perfect knowledge; he knows all persons and things; he knows himself, his perfections, purposes, thoughts, words and works; he knows all his creatures, animate and inanimate, rational and irrational, angels and men; the hearts of all men; all that they say, all their hard sayings, all their proud, haughty, overbearing expressions, calumnies, and reproaches, as well as all they think and all they do, good or bad; and God will sooner or later convince them of and punish them for their hard speeches against his people: and he is the author of all knowledge, natural, civil, spiritual, and evangelical: and by him actions are weighed: his own actions; his works "ad intra"; his purposes and decrees, the counsels of his will, and the thoughts of his heart, the things his mind is set upon; all his appointments and designs, his whole will and pleasure; all are pondered by him, and are formed with the utmost wisdom, and for the best ends and purposes: and all, his actions and works without, whether of creation, providence, and grace, all are weighed and done according to infinite wisdom, unerring justice and truth; all respecting things temporal or spiritual, what relate to the outward estate of men, or to their everlasting happiness: all the actions of men, as they are known unto him, they are weighed and examined by him, whether they proceed from a right principle to a right end or not; upon which, many actions, thought to be good, are not found to be so, and others, though good, yet not found perfect before God; so that there is no justification nor salvation by the best: or the sense is, such actions as are done well, they are "directed to him" (m); as they are ordained by him that men should walk in them, they are for his use, and are done with a view to his glory. There is a double reading of these words; the marginal, which we follow, is "to" or "by him" actions are directed or weighed; but the textual reading is a negative, "actions are not weighed" (n), or numbered; the works of God cannot be comprehended, or the actions of men are not disposed and ordered without his will and pleasure, or cannot be performed unless he wills or permits; and all are disposed of, overruled, and directed, to answer his own ends and purposes. (i) "durum", Vatablus, Drusius, Piscator; so R. Isaiah. (k) "Vetera", V. L. "vetus", Pagninus, Montanus. (l) "Deus scientiarum", V. L. Pagninus, Montanus, Tigurine version, Drusius. (m) "ipsi directa sunt", Pagninus. (n) "Non disponuntur", Junius & Tremellius; "non numerantur", so some in Vatablus; "non perficiuntur", so some in Munster.”

“Old. Hebrew hathak means also, “hard things.” (Du Hamel) — “Let arrogance come out of your mouth,” to return no more. Yet most people supply the negation from the former member; “Let not arrogance or hard things.” Chaldean, “blasphemy,” &c. (Calmet) — Cease to praise idols, as you have done. (Worthington) — Use not the malevolent language to which you have been accustomed. — Knowledge. The secrets of hearts are open to him. — And to him. Hebrew, “and by him actions are weighed,” as in scales; (Haydock) or, “thoughts (and actions) are not established.” (Symmachus) The Syriac and Arabic also read the negation, “there are not pretexts before him;” or, “are not actions founded upon him?” Will he not execute what he has wisely designed, in spite of opposition? (Haydock) — Septuagint, “and God prepares his thought;” (Calmet) ( epitedeumata autou ) or, “what is convenient for him.” (Haydock) — They have read lu, “of him,” instead of la, “not,” as they are authorized to do by the Keri, (or various readings in the margin) and by several Hebrew manuscripts. The Protestants think rightly, and suppose that la, “not,” has been omitted, “Let not arrogancy;” because we find it in Chaldean, Septuagint, Syriac and Arabic versions. Lu is substituted for la, ver. 16. When some have been pressed with the argument of variations, called Keri, they have said that they were rather explanations of obscure words in the text: but is there any obscurity in lu, “to him,” and la, “not;” or can they explain each other? Leusden answers in the affirmative, ver. 16! (Kennicott)”
