Arcana Coelestia #3449
3449. 'And Isaac said to them, For what reason have you come to me, seeing that you hate me and have sent me away from you?' means, Why should they desire that which is Divine seeing that they refused to recognize it and loathed that which is contained in the internal sense of the Word? This becomes clear from what has been stated above at verses 15-16, 19-21.
Arcana Coelestia #1231
1231. That 'Lud' means cognitions of truth is clear from the fact that cognitions of truth are obtained in this manner, namely from the Lord through charity and so through faith, by means of reason and knowledge. It is clear also in Ezekiel,
Persia and Lud and Put were in your army, as your men of war; they hung the shield and helmet in you, they gave you your splendour. Ezekiel 27:10.
This refers to Tyre. 'Lud and Put' stands for cognitions, which are spoken of as being 'in its army' and as being 'men of war' because cognitions with the support of reason serve to defend truths, which is also 'hanging the shield and helmet'. That 'Put' means exterior cognitions of the Word, see above at verse 6 of this chapter.
