Then Naomi her mother in law said unto her, My daughter, shall I not seek {a} rest for thee, that it may be well with thee?

(a) Meaning that she would provide her with a husband, with whom she might live peacefully.

Wesley's Notes

3:1 Rest - A life of rest, and comfort, and safety, under the care of a good husband.

Jamieson-Fausset-Brown Bible Commentary

CHAPTER 3

Ru 3:1-13. By Naomi's Instructions, Ruth Lies at Boaz's Feet, Who Acknowledges the Duty of a Kinsman.

Matthew Henry's Concise Commentary

3:1-5 The married state should be a rest, as much as any thing upon earth can be so, as it ought to fix the affections and form a connexion for life. Therefore it should be engaged in with great seriousness, with earnest prayers for direction, for the blessing of God, and with regard to his precepts. Parents should carefully advise their children in this important concern, that it may be well with them as to their souls. Be it always remembered, That is best for us which is best for our souls. The course Naomi advised appears strange to us; but it was according to the laws and usages of Israel. If the proposed measure had borne the appearance of evil, Naomi would not have advised it. Law and custom gave Ruth, who was now proselyted to the true religion, a legal claim upon Boaz. It was customary for widows to assert this claim, De 25:5-10. But this is not recorded for imitation in other times, and is not to be judged by modern rules. And if there had been any evil in it, Ruth was a woman of too much virtue and too much sense to have listened to it.
