John Gill Commentary Ruth 3:1

"And Naomi her mother-in-law said unto her, My daughter, shall I not seek rest for thee, that it may be well with thee?" — Ruth 3:1 (ASV)

Then Naomi her mother in law said to her
After the harvests were over, and so gleaning likewise; when Naomi and Ruth were together alone in their apartment, the mother addressed the daughter after this manner:

my daughter, shall I not seek for you, that it may be well with you ?
that is, in the house of an husband, as in (Ruth 1:9) her meaning is, to seek out for an husband for her, that she might have an house of her own to rest in, and an husband to provide her; that so she might be free from such toil and labour she had been lately exercised in, and enjoy much ease and comfort, and all outward happiness and prosperity in a marriage state with a good husband. This interrogation carries in it the force of a strong affirmation, may suggest that she judged it to be her duty, and that she was determined to seek out such a rest for her; and the Targum makes her way of speaking stronger still, for that is, by an oath I will not rest, until the time that I have sought a rest for you.''
