So, will it be right to say that God does not permit divorce under any circumstance?
He permits, though doesn't demand, it if the other partner has been unfaithful.
"And I say to you: whoever divorces his wife, except for sexual immorality, and marries another, commits adultery.” Matt 19:9
"I gave faithless Israel her certificate of divorce and sent her away because of all her adulteries. Yet I saw that her unfaithful sister Judah had no fear; she also went out and committed adultery." Jer 3:8
