Oil -- typically olive oil -- symbolizes the good that comes from celestial love. Celestial love is love of the Lord, the highest and purest love we can have. The good of celestial love is the desire to be good springing from celestial love: Wanting to do the Lord's will because you love Him. That's not a state many reach, even in heaven, but it's a beautiful goal. This representation makes sense based on the idea that the sun -- the source of all natural light and heat, and thus all natural life -- represents the Lord, the source of all spiritual light, heat and life. Burning oil was the most pure fire available in Biblical times, thus the closest representation of the sun people could create.

10376. 'The tablets of stone, written with the finger of God' means the Divine Truth there, coming from the Lord Himself. This is clear from the meaning of 'the tablets' as the law in its entirety, thus the Word, dealt with in 9416; from the meaning of 'stone' as Divine Truth on lowest levels, dealt with below; and from the meaning of 'being written with the finger of God' as coming from the Lord Himself, for what is written with anyone's finger comes from that person himself. The reason why those tablets were made of stone and the words of the law were written into the stone was that 'stone' means truth on lowest levels, and Divine Truth on lowest levels is the sense of the letter of the Word, containing the internal sense.

'Stone' means truth, see 643, 1298, 3720, 6426, 9476, and truth on lowest levels, 8609.
