Arcana Coelestia#4600
4600. 'And it happened while Israel was residing in that land' means during this state, namely that of good arising out of truth. This is clear from the meaning of 'residing' as living, for residing is similar in meaning to 'dwelling', the difference being that 'residing' has reference to truth but 'dwelling' to good - 'dwelling' meaning being and living, and so state, see 3384; and from the meaning of 'land' as the Church as regards good, dealt with in 566, 662, 1066, 1067, 1262, 1413, 1607, 1733, 1850, 2117, 2118, 2571, 2928, 3355, 4447, 4535, in this case as regards the good of truth. A state involving this good which Israel had now arrived at is the state meant here.

928. 'The imagination of man's heart is evil from his childhood' means that the will part of man's mind is totally evil. This is clear from what has just been stated. 'The imagination of the heart' has no other meaning. Man supposes that he has a will for good, but in this he is utterly mistaken. When he does good, he does not act from his own will but from the new will which is the Lord's, and thus from the Lord. Likewise when he thinks and utters what is true, he speaks from the new understanding deriving from that new will, and so again from the Lord. For one who has been regenerated is an entirely new person who has been formed by the Lord. This also is why he is said to have been created anew.
