Psalms 127:4

Verse 4 As arrows are in the hand of a mighty man - Each child will, in the process of time, be a defense and support to the family, as arrows in the quiver of a skillful and strong archer; the more he has, the more enemies he may slay, and consequently the more redoubted shall he be. Children of the youth - The children of young people are always more strong and vigorous, more healthy, and generally longer lived than those of elderly, or comparatively elderly persons. Youth is the time for marriage; I do not mean infancy or a comparative childhood, in which several fools join in marriage who are scarcely fit to leave the nursery or school. Such couples generally disagree; they cannot bear the boyish and girlish petulancies and caprices of each other; their own growth is hindered, and their offspring, (if any), have never much better than an embryo existence. On the other hand age produces only a dwarfish or rickety offspring, that seldom live to procreate; and when they do, it is only to perpetuate deformity and disease. It would be easy to assign reasons for all this; but the interpretation of Scripture will seldom admit of physiological details. It is enough that God has said, Children of the youth are strong and active, like arrows in the hands of the mighty.
