Malachi 2:15
Amplified Bible (AMP)
And did not God make [you and your wife] one [flesh]? Did not One make you and preserve your spirit alive? And why [did God make you two] one? Because He sought a godly offspring [from your union]. Therefore take heed to yourselves, and let no one deal treacherously and be faithless to the wife of his youth.— Malachi 2:15 (AMP)
