Romans 7:3
So then if, while her husband liveth, she be married to another man, she shall be called an adulteress: but if her husband be dead, she is free from that law; so that she is no adulteress, though she be married to another man.
So then if while her husband liveth,.... True indeed it is, that whilst her husband is alive, if
she be married to another man, she shall be called an adulteress; she will be noted and accounted of as such everybody, except in the above mentioned cases:
but if her husband be dead; then there can be no exception to her marriage:
she is free from the law; of marriage, by which she was before bound:
so that she is no adulteress; nor will any reckon her such; she is clear from any such imputation:
though she be married to another man; hence it appears that second marriages are lawful.
