241. Verse 18. I counsel thee, signifies the means of reformation of those who are in the doctrine of faith alone.

9151. 'If the thief is caught' means recollection. This is clear from the meaning of 'being caught', when said of truths and factual knowledge taken away out of the memory, as recollection; and from the meaning of 'the thief' as that which has been taken away, for 'thief' has the same meaning as 'theft', 9125, 9126.
