2247. 'Abraham still stood before Jehovah' means the Lord's thought from the Human which was joined to the Divine in the manner stated above. This is clear from the representation in this chapter of 'Abraham' as the Lord as regards the Human, and from its being said that he stood before Jehovah. From this it follows without explanation that it was the thought from the Human which was joined to the Divine in the manner stated at the start of this chapter, and also above in 2245.
