Psalmen 127:3

With הנּה it goes on to refer to a specially striking example in support of the maxim that everything depends upon God's blessing. פּרי הבּטן (Gen 30:2; Deu 7:13) beside בּנים also admits of the including of daughters. It is with בּנים (recalling Gen 30:18) just as with נהלת. Just as the latter in this passage denotes an inheritance not according to hereditary right, but in accordance with the free-will of the giver, so the former denotes not a reward that is paid out as in duty bound, but a recompense that is bestowed according to one's free judgment, and in fact looked for in accordance with a promise given, but cannot by any means be demanded. Sons are a blessed gift from above. They are - especially when they are the offspring of a youthful marriage (opp. בּן־זקנים, Gen 37:3; Gen 44:20), and accordingly themselves strong and hearty (Gen 49:3), and at the time that the father is growing old are in the bloom of their years - like arrows in the hand of a warrior. This is a comparison which the circumstances of his time made natural to the poet, in which the sword was carried side by side with the trowel, and the work of national restoration had to be defended step by step against open enemies, envious neighbours, and false brethren. It was not sufficient then to have arrows in the quiver; one was obligated to have them not merely at hand, but in the hand (בּיד), in order to be able to discharge them and defend one's self. What a treasure, in such a time when it was needful to be constantly ready for fighting, defensive or offensive, was that which youthful sons afforded to the elderly father and weaker members of the family! Happy is the man - the poet exclaims - who has his quiver, i.e., his house, full of such arrows, in order to be able to deal out to the enemies as…

This is a family-psalm, as divers before were state-poems and church-poems. It is entitled (as we read it) "for Solomon," dedicated to him by his father. He having a house to build, a city to keep, and seed to raise up to his father, David directs him to look up to God, and to depend upon his providence, without which all his wisdom, care, and industry, would not serve. Some take it to have been penned by Solomon himself, and it may as well be read, "a song of Solomon," who wrote a great many; and they compare it with the Ecclesiastes, the scope of both being the same, to show the vanity of worldly care and how necessary it is that we keep in favour with God. On him we must depend, I. For wealth (Psa 127:1, Psa 127:2). II. For heirs to leave it to (Psa 127:3-5). In singing this psalm we must have our eye up unto God for success in all our undertakings and a blessing upon all our comforts and enjoyments, because every creature is that to us which he makes it to be and no more. A song of degrees for Solomon.

127:3-5 Children are one of God’s blessings. The words translated “children” (Hebrew banim) and “builders” (bonim, 127:1) form a wordplay. Having children builds a family.
