to her sister] This is not to be understood onely of another naturall sister, as if a man might have two wives, so they were not such sisters; or two sisters one after another to wife, the latter upon the death of the former; for the marriage of the brothers wife is forbidden before, vers. 16. and by consequence, a woman must not marry her sisters husband; and so two sisters are already forbidden to be married to one man, vers. 16. Wherefore it is most probable, that this is a prohibition of Polygamie: that is, of having more wives then one at once; and the reason sheweth it, that the one may not be a vexation to the other, which is like to fall out not onely betwixt naturall sisters, as Leah and Rachell, Genesis 30:1. 14. but betwixt those that are not of kinne; as betwixt Hannah, and Peninnah, 1 Samuel 1:6. And for the word sister, in a generall acceptation it may be applied to any woman; as the word Brother, to any man, Genesis 19:7. and it is to be noted, that it is sometimes applied to things, which in propriety of speech, come not under such a title or denomination; as the wings of the beast, Ezekiel 1:9. are said to touch a woman to ber sister, as the Hebrew phrase carrieth it.
