Husband and wife:
Husband respect your wife also likewise the wife should respect the husband, they both should give what is due to each other.
1 Corinthians 7:5
Defraud ye not one the other except it be with consent for a time.
For example when a husband and wife wants to go into praying and fasting.
1 Corinthians 7:4
If you are a man you have no power over your own body for your body is for your wife like wise the wife because as a wife your body is for your husband, if he wants to kiss your sole do not deny him that because your body is his.
If you receive your salary share with your spouse for the both are one and are also ordained to help each other.
It has a very good relevance.
