Matthew 19:4-6

AUV(i) 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.”
