Psalms 127:4

As arrows [are] in the hand of a mighty man; so [are] children of the youth.

Ver. 4. As arrows are in the hand of a mighty man] Heb. of a giant, who shooteth them with a courage, and is cunning at it. As clean and well kept arrows. This similitude importeth that children must have more in them than nature; for arrows are no arrows by growth, but by art; so they must be such children, the knottiness of whose nature is refined and reformed, and made smooth by grace; and then they are cared for. As, if they prove otherwise, they are a singular heartbreak to their poor parents, who are seen to sit under Elijah's juniper, wishing for death, and saying, with Moses, Numbers 11:14,15, I am not able to bear all this sore affliction, "because it is too heavy for me. And if thou deal thus with me, kill me, I pray thee, out of hand, if I have found favour in thy sight; and let me not see my wretchedness."

So are children of the youth] Or, young sons, or lads, springlings, striplings, vegetous and vigorous, able to be a guard to their aged parents against the children of violence, who seek to press in upon them at the door, as the Sodomites dealt by righteous Lot, see Psa 127:5 besides the service they may do to the commonwealth (as did the Horatii and Curiatii) by their impetus heroici, valour and virtue.
