1 Corinthians 7:39-40 St Paul from the Trenches 1916 (GWC)

39. Lastly, a wife of course is bound to her husband for his life-time only — if he dies, she is free to marry again, but let her second choice not be one of the heathen, but one who belongs to the faith.

40. But, as I said before, I believe it to be better that she marry not again, but remain a widow, and in so saying I believe that my sense in this matter is governed by the Spirit of God.
