1 Corinthians 7:39; 1 Corinthians 9:14; 1 Corinthians 15:45

39 A wife is bound as long as her husband lives; but if her husband is dead, she is free to be married to whom she wishes, only in the Lord .
14 So also the Lord directed those who proclaim the gospel to get their living from the gospel.
45 So also it is written, "The first MAN, Adam, BECAME A LIVING SOUL." The last Adam became a life-giving spirit.
