being here expanded and unfolded. There it appears as a gift of grace in contrast to the God-estranged self-activity of man, here as a fruit of the ora et labora. Ewald considers this and the preceding Psalm to be songs to be sung at table. But they are ill-suited for this purpose; for they contain personal mirrorings instead of petitions, and instead of benedictions of those who are about to partake of the food provided.
Verses 1-3
The כּי in Psa 128:2 signifies neither “for” (Aquila, κόπον τῶν ταρσῶν σου ὅτι φάγεσαι), nor “when” (Symmachus, κόπον χειρῶν σου ἐωθίων); it is the directly affirmative כּי, which is sometimes thus placed after other words in a clause (Psa 118:10-12, Gen 18:20; Gen 41:32). The proof in favour of this asseverating כּי is the very usual כּי עתּה in the apodoses of hypothetical protases, or even כּי־אז in Job 11:15, or also only כּי in Isa 7:9, 1Sa 14:39; “surely then;” the transition from the confirmative to the affirmative signification is evident from Psa 128:4 of the Psalm before us.

In close connection with this is the prosperity of a house that is at peace and contented within itself, of an amiable and tranquil and hopeful (rich in hope) family life. “Thy wife (אשׁתּך, found only here, for אשׁתּך) is as a fruit-producing vine.” פּריּה for פּרה, from פּרה = פּרי, with the Jod of the root retained, like בוכיּה, Lam 1:16. The figure of the vine is admirably suited to the wife, who is a shoot or sprig of the husband, and stands in need of the man's support as the vine needs a stick or the wall of a house (pergula). בּירכּתי ביתך does not belong to the figure, as Kimchi
