John Calvin Commentary Genesis 30:2

"And Jacob`s anger was kindled against Rachel: and he said, Am I in God`s stead, who hath withheld from thee the fruit of the womb?" — Genesis 30:2 (ASV)

And Jacob’s anger was kindled. Jacob’s tender affection made him reluctant to offend his wife; yet her unworthy conduct compelled him to do so when he saw her petulantly exalting herself, not only against her sister, who piously, humbly, and thankfully was enjoying God’s gifts, but even against God Himself, of whom it is said that the fruit of the womb is his reward (Psalms 127:3).

For this reason, therefore, Jacob is angry, because his wife ascribes nothing to God’s providence and, by imagining that children are the offspring of chance, would deprive God of the care and government of mankind. It is probable that Jacob had already been sorrowful because of his wife’s barrenness. Therefore, he now fears that her folly might further provoke God’s anger to inflict more severe strokes. This was a holy indignation, by which Jacob maintained the honor due to God, while he corrected his wife and taught her that it was not without sufficient cause that she had been barren until now. For when he affirms that the Lord had shut her womb, he subtly implies that she ought to humble herself more deeply.
