“Let us now come to the words, "Thy wife" [Psalm 128:3]: it is said unto Christ. His wife, therefore, is the Church: His Church, His wife, we ourselves are. "As a fruitful vineyard." But in whom is the vineyard fruitful? For we see many barren ones entering those walls; we see that many intemperate, usurious persons, slave dealers, enter these walls, and such as resort to fortune-tellers, go to enchanters and enchantresses when they have a headache. Is this the fruitfulness of the vine? Is this the fecundity of the wife? It is not. These are thorns, but the vineyard is not everywhere thorny. It hath a certain fruitfulness, and is a fruitful vine; but in whom? "Upon the sides of thy house." Not all are called the sides of the house. For I ask what are the sides. What shall I say? Are they walls, strong stones, as it were? If he were speaking of this bodily tenement, we should perhaps understand this by sides. We mean by the sides of the house, those who cling unto Christ...."Thy children." The wife and the children are the same. In these carnal marriages and wedlocks, the wife is one, the children other: in the Church, she who is the wife, is the children also. For the Apostles belonged to the Church, and were among the members of the Church. They were therefore in His wife, and were His wife according to their own portion which they held in His members. Why then is it said concerning them, "When the Bridegroom shall be taken from them, then shall the children of the Bridegroom fast"? She who is the wife, then, is the children also....”

“as a fruitful vine Every woman whose blood is abundant will have many children. in the innermost parts of your house Because it is customary to have marital relations in secret. Another explanation: in the innermost parts If your wife is menstruating, put her into the innermost parts of your house so that you will not become accustomed to being with her. your sons will be like olive shoots Just as olive trees cannot be grafted, so will your sons not have any disqualification.”

“Thy wife shall be as a fruitful vine by the sides of thine house,.... The vine being a weak and tender tree, which needs propping and supporting; and often is fastened to the sides of a house, to which the allusion here is; whereunto it cleaves, and on which it runs up, and bears very agreeable fruit; it is properly used to express the weakness and tenderness of the female sex, their fruitfulness in bearing children, and their care of domestic affairs, being keepers at home; see Pe1 3:7. Kimchi observes, that the vine is the only tree men plant within doors; which, when it is grown up, they bring out at a hole or window of the house without, to have the sun and air; and so its root is within the house, and the branches without: and he observes, that a modest woman is within the house, and does not go without, and is only seen by her husband; but her children, like the branches of the vine, go out to work. This may be applied to Christ and his church; to him the other characters agree: he, as man, is one that feared the Lord; the grace of fear was in him; the spirit of fear rested on him; and he was in the exercise of it, and walked in all the ways of the Lord, Isa 11:1; he now sees and enjoys the travail or labour of his soul to satisfaction, and is made most blessed for evermore, Isa 53:11. The church is the bride, the Lamb's wife, the spouse of Christ; and may be compared to a vine for her weakness in herself, her fruitfulness in grace and good works, and in bringing forth souls to Christ, through the ministry of the word; all which is pleasant and grateful to him; see Psa 80:14; thy children like olive plants round about thy table; a numerous offspring was always accounted a very great blessing; and it must be very pleasant to a parent to see his children round about his table, placed in their proper order according to their age, partaking of what it is furnished with: Job, in his time of prosperity, had many children; and, next to the presence of the Almighty with him, he mentions this of his children being about him; see Job 1:2. This may be applied to the spiritual seed and offspring of Christ, which are like to olive trees or olive plants; to which David is compared, Psa 52:8; the two anointed ones in Zac 4:11; the two witnesses in Rev 11:4; and all true believers in Christ may; because of their excellency, these being choice plants; because of their fruitfulness and beauty; because of their fatness, and having oil in them; and because of their perpetuity, being ever green; see Jer 11:16. Now Christ has a table, which he has well furnished, at which he himself sits, and places these his children all around; and whom he welcomes to the entertainment he makes, and takes delight and pleasure in them, Sol 1:12. Kimchi observes, the olive trees do not admit of a graft from other trees; see Rom 11:24; and so this denotes the legitimacy of those children, being free from all suspicion of being spurious, being born of such a wife as before described; and being green and moist all the year long, denotes their continuance in good works.”

“Sides. Against which vines were planted. (Calmet) — The married people who fear God, shall commonly have a numerous posterity; or their souls shall produce many good works in the Church, which springs from our Saviour’s side. Children denote such good works. (Worthington) — Plants. Psalm cxliii. 12. (Homer, Odyssey vi. 163.)”
