Arcana Coelestia #10641
10641. 'Lest by chance it become a snare in your midst' means consequently being led astray in the Word itself. This is clear from the meaning of 'becoming a snare' as being held captive and led astray by one's own evil and falsity, dealt with in 7653, 9348; and from the representation of 'Moses' as the Word, dealt with in the places referred to in 9372, so that 'in his midst' means in the Word itself. The implications of this are clear from what has been stated immediately above in 10640.
Arcana Coelestia #7653
7653. 'How long will this thing be a snare to us?' means that by behaving in that way they would be held captive by their own evil. This is clear from the meaning of 'this thing being a snare' as being held captive by their own evil, and so being led into the misery that punishment brings.
