Midrash su Salmi 128:3

R. Phinehas the priest, the son of Hama, declared: A woman who is modest in her home atones for her household, just as the altar brings atonement, as it is said: Thy wife shall be a fruitful vine in the innermost parts of thy house (Ps. 128:3). The word innermost refers here to the altar, as is stated: And he shall kill it on the innermost side of the altar (Lev. 1:11).

Another comment on Thy wife shall be a fruitful vine. When is a wife considered a fruitful vine? When she remains secluded in the innermost parts of thy house (Ps. 128:3). If she does so, Thy children shall be like olive plants about thy table (ibid.), that is, she will rear children who will be anointed with the oil of installation.

6) "and I will break the bars of your yoke": To what may this be compared? One has a cow that he plows with and he lends it to another to plow with. That man has ten sons. This one comes and plows with it and leaves, and that one comes and plows with it and leaves — until the cow is exhausted and buckles under. All the cows (i.e., all the nations) enter and that cow (Israel) does not enter. It does not wait to be freed (of its yoke) by that man; but He comes immediately and breaks the yoke and cuts the yoke thongs. So, Israel in this world. One power comes and subjugates her and leaves, and another power comes and subjugates her and leaves. And the furrow is long, as it is written (Tehillim 128:3) "Plowmen have plowed on my back; they have lengthened their furrow." Tomorrow, when the end arrives, the Holy One Blessed be He will not tell the nations: "This and this is what you have done to My children." But immediately He will come and break the yoke and cut the yoke thongs, as it is written "And I will break the bars of your yoke." And thus is it written (Tehillim, Ibid. 4) "He has cut the cords of the wicked."
