1 Corinthians 7:36

But if any man thinketh that he behaveth himself unseemingly toward his virgin daughter, if she be past the flower of her age, and if need so requireth, let him do what he will; he sinneth not; let them marry.

'that he behaveth himself unseemingly toward his virgin (daughter)' -'is not acting properly' (Gspd) 'The arranging of marriages by parents wasn't. Pauline invention. He took it as he found it.' (McGuiggan pp. 117-118)

Apparently the "unseemingly" behaviour, would be not allowing. daughter to marry, who isn't cut out for the celibate life. (1 Corinthians 7:2)

'past the flower of her age' -'beyond the peak, bloom, zenith, etc..', here the word refers to full sexual maturity. (Lenski p. 326); 'Past her youth' (TCNT) 'With women it frequently is used to refer to "coming of age", especially puberty..for the woman, therefore, it would mean either that she is getting "past her prime", or "was fully developed sexually., and therefore ready for marriage.' (Fee p. 352)

'and if need so requireth' -'if it must be so' (NASV), i.e. 1 Corinthians 7:9 and 1 Corinthians 7:2. 'and so the matter is urgent' (Mon); 'and it has to be' (RSV)
