A sermon on the Book of Ruth

It is common to say that the act of redemption described in the Book of Ruth is not redemption but redemption, that is, an ancient custom in which relatives redeemed the wife of their deceased relative… However, from a review of the Maharsha's words on the issue of redemption from a deceased relative who fell into redemption, it seems that he believes that in biblical times, redemption from the Torah was practiced for other relatives as well… What do you think???
