John Wesley on Joshua 2:12

By the Lord - By your God who is the only true God: so she owns his worship, one eminent act whereof is swearing by his name. My father's house - My near kindred, which she particularly names, Jos 2:13, husband and children it seems she had none. And for herself, it was needless to speak, it being a plain and undeniable duty to save their preserver. True token - Either an assurance that you will preserve me and mine from the common ruin: or a token which I may produce as a witness of this agreement, and a means of my security. This is all that she asks. But God did for her more than she could ask or think. She was afterwards advanced to be a princess in Israel, the wife of Salmon and one of the ancestors of Christ.
