In Genesis 4:23, this signifies to extinguish faith. (Arcana Coelestia 427)

'The slain of Jehovah' signify people who turn truths into falsities, which causes them to perish.

'The slain,' in Lamentations 2:12 signify people who do not know what the truths of faith mean.

'The slain' when referring to the Lord in Revelation 5 means the separation of everything from the divine. In denial of His divinity, He is spiritually slain to people and this denial causes a state of separation from Him.

4469. 'And if you do not listen to us to be circumcised' means unless they forsook their own truths and accepted external representatives. This is clear from what has been explained above in 4462. The statements made in these verses by Jacob's sons carry a meaning which is the opposite of that which Hamor and Shechem had in mind, and therefore also that which is the opposite in the internal sense, as shown by the explanations given. The reason for this is as stated in verse 13, that they spoke deceitfully, and the thoughts and feelings of one who speaks deceitfully are different from those of the one to whom he is speaking, 4459.
