And Naomi took the child, placed him on her lap, and became a nurse to him.
Here is, I. Ruth a wife. Boaz took her, with the usual solemnities, to his house, and she became his wife (Rut 4:13), all the city, no doubt, congratulating the preferment of a virtuous woman, purely for her virtues. We have reason to think that Orpah, who returned from Naomi to her people and her gods, was never half so well preferred as Ruth was.
Commenting on Ruth 4:13-22
And Naomi took the child, and laid it in her bosom,.... As a token of her most tender love and affection for it; this it is probable she did quickly after the birth of it: and became a nurse unto it; that is, after the mother had suckled and weaned it, then she took it from her, and brought it up.
Naomi took the child - This might do for Naomi, but it was bad for the child. A child, unless remarkably healthy and robust, will suffer considerably by being nursed by an old woman, especially if the child sleep with her. The aged gain refreshment and energy by sleeping with the young; and from the same means the young derive premature decrepitude.
