Ruth 4:5

And Boaz said, In the day when thou acquirest the land from the hand of Naomi, and from Ruth the Moabitess, (in that day) thou hast acquired the wife of the deceased, to establish the name of the deceased upon his inheritance. So we would punctuate and render this verse. Boaz distinctly informed his relative that if the land was acquired at all by a kinsman, it must be acquired with its living appurtenance, Ruth the Moabitess, so that, by the blessing of God, the Fountain of families, there might he the opportunity of retaining the possession of the property in the line of her deceased husband, that line coalescing in the line of her second husband. It was the pleasure of Naomi and Ruth, in offering their property for sale, to burden its acquisition, on the part of a kinsman, with the condition specified. If there should be fruit after the marriage, the child would be heir of the property, just as if he had been Machlon's son, even though the father should have other and older sons by another wife.
