1 Corinthians 7:1-3

Amplified Bible

Teaching on Marriage

7 Now as to the matters of which you wrote: It is good (beneficial, advantageous) for a man not to touch a woman [outside marriage]. ² But because of [the temptation to participate in] sexual immorality, let each man have his own wife, and let each woman have her own husband. ³ The husband must fulfill his [marital] duty to his wife [with good will and kindness], and likewise the wife to her husband.
