Children are indeed a heritage from the LORD, and the fruit of the womb is His reward.
PSALM 127 This Psalm shows that the order of society, both political and domestic, is maintained solely by the blessing of God, and not by the policy, diligence, or wisdom of men; and that the procreating of children is his peculiar gift. A Song of Degrees of Solomon. Psalm 127:1-2 1.
Commenting on Psalm 127:1-5
Lo, children are an heritage of the Lord. This points to another mode of building up a house, namely, by leaving descendants to keep our name and family alive upon the earth. Without this what is a man's purpose in accumulating wealth! To what purpose does he build a house if he has none in his household to hold the house after him?
We are here taught to have a continual regard to the divine Providence in all the concerns of this life. Solomon was cried up for a wise man, and would be apt to lean to his own understanding and forecast, and therefore his father teaches him to look higher, and to take God along with him in his undertakings.
