Matthew 19:5

On Divorce

⁴ And He answered them, "Have you not read [Gen. 1:27; 5:2] that when God created [mankind as] male and female, ⁵ He said [Gen. 2:24], 'For this reason [i.e., since He made one woman for one man], a man will leave [the home of] his father and mother and will cling to his wife, [so that] the two of them will [then] become one flesh [i.e., united in such a close relationship as to constitute one body]?' ⁶ So, [upon becoming husband and wife] they no longer function [entirely] as two persons, but [as] one body. Therefore, those whom God [so] joins together [in the marriage bond], no person must [ever] separate."

[Gen. 2:24 says], "For this reason a man will leave [the home of] his father and mother, and will cling to his wife, [so that] the two will become one flesh [i.e., united in such a close relationship, as to practically constitute one body]."

But, because of so much sexual immorality, each man should have his own wife and each woman her own husband.

1 Corinthians 7:4

The wife does not have [sole] authority over her own [physical] body, but the husband [also has his right to it]. And in the same way, the husband also does not have [sole] authority over his own [physical] body, but the wife [i.e., has her right to it, as well].
