'Partner' in the Bible
Whoever is partner with a thief hates his own life;He hears the curse [when swearing an oath to testify], but discloses nothing [and commits perjury by omission].
And we know [with great confidence] that God [who is deeply concerned about us] causes all things to work together [as a plan] for good for those who love God, to those who are called according to His plan and purpose.
But if the unbelieving partner leaves, let him leave. In such cases the [remaining] brother or sister is not [spiritually or morally] bound. But God has called us to peace.
