John Calvin Commentary Psalms 113:9

"He maketh the barren woman to keep house, [And to be] a joyful mother of children. Praise ye Jehovah." — Psalms 113:9 (ASV)

Who makes the barren woman to dwell in the family. He relates another work of God, which, though apparently not as notable, should not, for that reason, engage our thoughts any less. Unimpressed as we are by the ordinary works of God, we are compelled to express our astonishment when a woman who has been barren for a long period unexpectedly becomes the mother of a numerous family.

The Hebrew term, הבית, habbayith, should be understood not simply as a house but also as a household (that is, the container for what is contained), just as the Greeks apply οικος, and the Latins domus, to a household. The meaning is that the woman who was formerly barren is blessed with fruitfulness and fills the house with children.

He attributes joy to mothers because, though the hearts of all are inclined to desire wealth, honor, pleasures, or any other advantages, yet progeny is preferred to everything else. Therefore, since God oversees the ordinary course of nature, changes the course of events, lifts up those in lowly circumstances and of humble origin, and makes the barren woman fruitful, our insensitivity is very blameworthy if we do not carefully consider the works of His hand.
