Ruth 1:13

Would you tarry for them till they were grown?
&c.] It is not to be thought that they would tarry till she was married and had children, and then till these infants were grown up to men's estate, and be marriageable; for though Tamar tarried for Shelah, yet he was born, and of some years of age, though not a grown man, ( Genesis 38:11 Genesis 38:14 )

would ye stay for them from having husbands?
they were young widows, and it was fit they should marry again; and it could not be imagined that they would deny themselves having husbands, in expectation of any sons of her's:

nay, my daughters;
I am well satisfied you will never tarry for them, nor deprive yourselves of such a benefit; it is unreasonable to suppose it:

for it grieveth me much for your sakes;
that she could be of no manner of service to them, either to give them husbands, or to support and maintain them, should they go with her; or "I have exceedingly more bitterness than you" ^F4; her condition and circumstances were much worse than theirs; for though they had lost their husbands, she had lost both husband and children: or it was more bitter and grievous to her to be separated from them, than it was for them to be separated from her; her affection to them was as strong, or stronger than theirs to her; or they had friends in their own country that would be kind to them, but as for her, she was in deep poverty and distress, and when she came into her own country, knew not that she had any friends left to take any notice of her:

that the hand of the Lord is gone out against me;
in taking away her husband and children, and reducing her to a low estate, penniless and friendless; so poor, as it appears, that her daughter-in-law, when come to the land of Canaan, was obliged to glean for the livelihood of them both, as in the next chapter.
