So they went and made the tomb secure, and along with [stationing] a guard of soldiers [to be on watch] they set a seal on the stone.

As we were staying there for some time, a prophet named Agabus came down from Judea.

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.
