(4) Children of the youth--i.e., the offspring of an early marriage. Aquila, "sons of young and vigorous parents." The young man, with his numerous family around him, is like the vigorous warrior with his quiver full of arrows.

Verse 4. - As arrows are in the hand of a mighty man; so are children of the youth; rather, the children of youth; i.e. children born to a man in his youth. Such children protect their aged parents as effectually as arrows in the hand of a warrior.

127:1-5 The value of the Divine blessing. - Let us always look to God's providence. In all the affairs and business of a family we must depend upon his blessing. 1. For raising a family. If God be not acknowledged, we have no reason to expect his blessing; and the best-laid plans fail, unless he crowns them with success. 2. For the safety of a family or a city. Except the Lord keep the city, the watchmen, though they neither slumber nor sleep, wake but in vain; mischief may break out, which even early discoveries may not be able to prevent. 3. For enriching a family. Some are so eager upon the world, that they are continually full of care, which makes their comforts bitter, and their lives a burden. All this is to get money; but all in vain, except God prosper them: while those who love the Lord, using due diligence in their lawful callings, and casting all their care upon him, have needful success, without uneasiness or vexation. Our care must be to keep ourselves in the love of God; then we may be easy, whether we have little or much of this world. But we must use the proper means very diligently. Children are God's gifts, a heritage, and a reward; and are to be accounted blessings, and not burdens: he who sends mouths, will send meat, if we trust in him. They are a great support and defence to a family. Children who are young, may be directed aright to the mark, God's glory, and the service of their generation; but when they are gone into the world, they are arrows out of the hand, it is too late to direct them then. But these arrows in the hand too often prove arrows in the heart, a grief to godly parents. Yet, if trained according to God's word, they generally prove the best defence in declining years, remembering their obligations to their parents, and taking care of them in old age. All earthly comforts are uncertain, but the Lord will assuredly comfort and bless those who serve him; and those who seek the conversion of sinners, will find that their spiritual children are their joy and crown in the day of Jesus Christ.As arrows are in the hand of a mighty man,.... Are shot out with great strength; come with much force, and do execution, and do not return in vain; with which men defend themselves, and annoy their enemies; see Jeremiah 50:9;

so are children of the youth: not young children, or children in their youth; but such who are born to their parents when they are in their youth; and which are generally healthful and strong, and their parents live to see them grown up; and who are useful to protect them, and defend their persons and properties from enemies when grown old and feeble, and unable to defend themselves: whereas children born to them in old age are generally unhealthy and weak; and besides, their parents rarely live to see them brought up, or to be helpful to them. So Christ's spiritual seed and offspring, who are the dew of his youth, are strong, and overcome the evil one; and are serviceable in the defence of his cause and interest.
