They that were full before have hired out themselves for bread: and the hungry are filled, so that the barren hath borne many: and she that had many children is weakened.

“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.”

“The sated have hired themselves out for bread. [The sated] who do not need to hire themselves out for any work, He starves them and they must hire themselves out for bread, And the hungry Who would toil and weary themselves for food. Have ceased. From their toil. Until the barren has born seven and she with many children…. While the barren woman has born seven, she that had many children has been bereaved and buries her children. Chana bore seven as it is stated, "For Adonoy remembered Chana and she conceived and gave birth to three sons and two daughters." When Chana bore one, Penina buried two. Penina had ten children as it is stated, "Am I not better to you than [the] ten sons of Penina?" When Chana bore four, Penina buried eight. When she [Chana] conceived and bore a fifth child, Penina prostrated herself at her feet and begged for mercy and they lived and were therefore considered as hers. This is R. Nechemya's opinion. R. Yehudah however says that grandchildren are considered as children. Some are of the opinion that the numerical value of שִׁבְעָה(377) is equivalent to that of שְׁמוּאֵל(377).”

“They that are full have hired out themselves for bread,.... Such as have been full of the good things of this life have been stripped of all, and reduced to such circumstances as to be obliged to hire themselves out to persons to labour under them for their bread. Hannah has either respect to some instances she had known, or prophesies of what would be hereafter, and was fulfilled in the Israelites, when in the hands of the Egyptians and Assyrians, Lam 4:6 and may be exemplified in the case of the prodigal son, Luk 15:13 and is true of such who have larger gifts, but not grace, and which they exercise for lucre sake, and are mere hirelings; and of self-righteous persons who are full of themselves, of their goodness and righteousness, purity, and power; are quite mercenary do all they do for gain, work for life, and labour for perishing meat, and for that which is not bread, and is unsatisfying: and they that were hungry ceased; that is, from being hungry, being filled with good things, having a large and sufficient supply to satisfy their craving desires, Luk 1:53. Such are the changes sometimes in Providence, that those who have lived in great plenty and fulness are obliged to work for their bread; and, on the other hand, such as have been starving, and in furnishing circumstances, have been brought into very plentiful and affluent ones. The "hungry", in a spiritual sense, are such who hunger an thirst after Christ, and his righteousness, for justification before God; after him and his blood for the remission of their sins, and the cleansing of their souls; after him, and salvation by him, in whom alone it is to be had; after a view of interest in him, and a greater degree of knowledge of him; and after more communion with him in his word and ordinances; and after the enjoyment of them for that purpose: now when they enjoy what they are craving after, they cease to hire out themselves for bread, as others do; they do not cease from working, but from dependence on their works, on which they cannot feed and live, having found and got other and better bread to feed upon; they cease to be hungry, for they are filled and satisfied with the love of God, with the righteousness of Christ, with the blessings of grace, and salvation by him, with the goodness of his house, and with all the fulness of God and Christ; and so having what satisfies them, they desire no other food, shall have no more want, or be in a starving condition any more, especially this will be the case hereafter: so that the barren hath born seven; meaning herself, who had born many, even five children besides Samuel, Sa1 2:20 which either was the case before this song was delivered; or rather what she believed would be the case after Eli had blessed her, and prayed for the children by her; seven being a number put for many, Pro 24:16. and she that hath many children is waxed feeble; and incapable of bearing more; and stripped of what she had; this may be understood of Peninnah, concerning whom the Jews have this tradition (o), which Jarchi relates, that when Hannah bore one child, Peninnah buried two; and whereas Hannah had five, Peninnah lost all her ten children. This may be applied to the case of the Gentile and Jewish churches, under the Gospel dispensation, when more were the children of the desolate or barren, the Gentiles, than of the married wife, the Jews, Isa 54:1. (o) Vid. Hieron, Trad. Heb. in. lib. Reg. fol. 34. K.”

“They that were full - All the things mentioned in these verses frequently happen in the course of the Divine providence; and indeed it is the particular providence of God that Hannah seems more especially to celebrate through the whole of this simple yet sublime ode.”

“Many. Hebrew, “seven,” which is often used in the same sense. Anna had never more than six children; (Calmet) whereas Phenenna had perhaps ten, chap. i. 8., and iii. 21. (Haydock) — The Rabbins pretend that she lost one every time that Anna brought forth. But the text says nothing of the kind. It only insinuates at most, that she had no more. This admirably represents the state of the Synagogue, compared to the Christian Church. (St. Augustine, sup.) (Calmet; Worthington) — The blessed Virgin conveys the same idea in other words, Luke i. (Menochius)”
