In John 8:2-11, when the woman taken in adultery was brought before him, the Lord wrote twice on the ground. This signifies the condemnation of the scribes and Pharisees for adulteries in a spiritual sense, they having adulterated the goods and falsified the truths of the Word. (Apocalypse Explained 222)

2834. 'And offered it as a burnt offering instead of his son' means their sanctification and adoption. This is clear from the meaning of 'offering as a burnt offering' as being sanctified, dealt with in 2776, and from the meaning of 'instead of his son' as being adopted, that is to say, by the Lord's Divine Human, meant here by 'Abraham', 2833. The adoption of those who were spiritual is described in John,

Jesus said, I am the vine, you are the branches. He who abides in Me, and I in him, he it is that bears much fruit, for without Me you can do nothing. John 15:5.

'The vine' is the spiritual Church, see 1069.
