1 Corinthians 7:36-39

Moffatt(i) 36 At the same time, if any man considers he is not behaving properly to the maid who is his spiritual bride, if his passions are strong and if it must be so, then let him do what he wants — let them be married; it is no sin for him. 37 But the man of firm purpose who has made up his mind, who, instead of being forced against his will, has determined to himself to keep his maid a spiritual bride — that man will be doing the right thing. 38 Thus both are right alike in marrying and in refraining from marriage, but he who does not marry will be found to have done better. 39 A woman is bound to her husband during his lifetime; but if he dies, she is free to marry anyone she pleases — only, it must be a Christian.
