The Lord, in the simplest terms, is love itself expressed as wisdom itself. In philosophic terms, love is the Lord's substance and wisdom is His form. Of course, we feel the Lord's love and hear His wisdom in many different ways, depending on our state in life and how receptive we are. That's why the Lord has so many different names in the Bible, and is referred to in so many different ways.

9373. 'Come up to Jehovah' means being joined to the Lord. This is clear from the meaning of 'coming up' as being raised to more internal things, dealt with in 3084, 4539, 4969, 5406, 5817, 6007, and therefore also being joined to them, 8760. The reason why it is a joining to the Lord is that 'Jehovah' in the Word means the Lord, 1343, 1736, 1793, 2004, 2005, 2018, 2025, 2921, 3023, 3035, 5663, 6280, 6281, 6303, 6905, 8274, 8864, 9315. A further arcanum which lies concealed within the internal sense of these words is that the children of Jacob, over whom Moses presided as their head, were not called or elected; rather, they themselves insisted that Divine worship should be established among them, as accords with what has been stated in 4290, 4293. This is why it says, And He said to Moses, Come up to Jehovah, as though not Jehovah but another was telling him to go up. For the same reason it says in what follows that the people should not come up, verse 2, and that Jehovah did not lay a hand on the children of Israel who had been set apart, verse 11; also that the sight of Jehovah's glory was like a consuming fire on the top of the mountain in the eyes of the children of Israel, verse 17; and finally that Moses, when he was called on the seventh day, went into the middle of the cloud, [verses 16, 18.] 'The cloud' means the Word in the letter, 5922, 6343 (end), 6752, 6832, 8106, 8443, 8781; and among the children of Jacob it was the Word separated from its internal sense, since their worship was external devoid of anything internal. This becomes perfectly clear from the fact that they now said, as they had done before [at Exodus 19:8], All the words which Jehovah has spoken we will do, verse 3; yet scarcely forty days went by after this time and they were worshipping the golden calf instead of Jehovah. From this it is evident that such idolatry lay concealed in their heart when they said with their lips that they would serve Jehovah alone. However, the people who are meant by the called and the elect are those with whom internal worship exists, and also external worship springing from internal, that is, those with whom love to the Lord and faith in Him, and consequently love towards the neighbour are present.
