Arcana Coelestia # 9153
9153. 'If the thief is not caught' means, if there is no recollection of what has been taken away. This is clear from the meaning of 'if the thief is caught' as, if there is a recollection of what has been taken away, dealt with just above in 9151, at this point no recollection of it since it says 'if he is not caught'.
Matthew 18:15-17
15
"If your brother sins against you, go, show him his fault between you and him alone. If he listens to you, you have gained back your brother.
16
But if he doesn't listen, take one or two more with you, that at the mouth of two or three witnesses every word may be established.
17
If he refuses to listen to them, tell it to the assembly. If he refuses to hear the assembly also, let him be to you as a Gentile or a tax collector.
