'Marital' in the Bible

He did not have marital relations with her until she had given birth to a son; and he named him Jesus.

A husband should fulfill his marital responsibility to his wife, and likewise a wife to her husband.

Do not deprive each other [of marital rights], except perhaps by mutual consent for a time, so that you may devote yourselves [unhindered] to prayer, but come together again so that Satan will not tempt you [to sin] because of your lack of self-control.
