John Gill Commentary Ruth 2:10

"Then she fell on her face, and bowed herself to the ground, and said unto him, Why have I found favor in thy sight, that thou shouldest take knowledge of me, seeing I am a foreigner?" — Ruth 2:10 (ASV)

Then she fell on her face, and bowed herself to the ground ,
&c.] In great humility, and under a deep sense of the favour done her, and as showing the greatest respect, in a civil manner, she was capable of:

and said unto him, why have I found grace in your eyes :
how is it that one so mean and unworthy should have such favour shown?

that you should take knowledge of me ;
take such notice of her, show such affection to her, and bestow such kindness on her:

seeing I am a stranger ?
not a citizen of Bethlehem, nor indeed one of the commonwealth of Israel; but, as the Targum, ``of a strange people, of the daughters of Moab, and of a people who were not fit and worthy to enter into the congregation of the Lord.''
