Like arrows in the hand of a warrior, so are children born in one’s youth.
Children born in youth become arrows in their father's hand, flying where he cannot go and striking the mark he aims at. You must shape them straight while they are young, or they will prove crooked and useless when grown; train them to the right point from the beginning.
AI summary
As arrows [are] in the hand of a mighty man; so [are] children of the youth. (f) That is, endued with strength and virtues from God: for these are signs of God's blessings, and not the number.
Children born to parents in their youth are like arrows in a warrior's hand: strong, healthy, and useful to defend their aging parents when feeble. Those born in old age are generally weak, and their parents rarely live to see them grown and helpful.
