There are really two meanings for "build" in the Bible. When something is being built for the first time, or built in the most typical sense, it means collecting relatively external ideas to build up a doctrinal system. In other cases, though, "build" is used in reference to something that has been destroyed. In such cases, "build" refers to removing our desires for evil so we can began a new stage of spiritual growth. In these cases "build" is often used together with "raise up," which means removing false ways of thinking in the same process.

9422. 'Sit for us in this [place]' means that they are to remain with this sense. This is clear from the meaning of 'sitting in this' - that is to say, in this place, or below the mountain - as remaining with the outward sense. 'Sitting in a place' means remaining with one's state, and 'below the mountain' means restricted to the outward sense of the Word. For 'sitting' means remaining, as will be clear from what follows below; 'place' means state; and 'Mount Sinai' means the law or Divine Truth emanating from the Lord, and so means the Word, 9420. The peak of the mountain, where Jehovah or the Lord was, Exodus 19:20, means the highest or inmost level of the law or the Word, 8827; the rest of the mountain beneath the peak means the inner level of the law or the Word as it exists in heaven; and the parts beneath the mountain, where the elders and the people were, means the outward level of the law or the Word, which is its outward sense. Thus in the Word the inmost, the inward, and the outward levels of things meant by 'the mountain' are represented, at this point the inmost, the inward, and the outward levels of the law or the Word, because 'Mount Sinai' means the law or the Word, 9420. From all this it is evident that 'Sit for us in this [place]' means that they are to remain with the outward sense.

[2] The word 'sit' is used because 'sitting' means remaining in a state; for movement from one place to another means changes of state involving the interiors, as becomes clear from what has been shown in 2837, 3356, 3387, 4321, 4882, 5605, 7381, and therefore sitting down means remaining in a state involving the interiors. Because 'sitting' has this meaning it was an accepted religious custom among the children of Israel to sit whenever they represented a state of the interiors that was permanent, as in the Book of Judges,

The children of Israel came to Bethlehem and wept; and they sat there before Jehovah and fasted that day until evening. Judges 20:26.

And elsewhere,

The people came to Bethlehem and sat there before God until evening; and they lifted up their voice and wept with great weeping. Judges 21:2.

In these verses 'sitting' means remaining long in a state of grief.

[3] This makes clear why the word 'sit' is used and what it implies in the following places: In David,

O Jehovah, You know my sitting down and my rising up; You understand my thought afar off. Psalms 139:2.

In Jeremiah,

You shall not go into the house of feasting to sit with them. Jeremiah 16:8.

In Micah,

Then He will stand and feed [His flock] in the strength of Jehovah, in the excellence of the name of Jehovah his God; and they will sit down. Micah 5:4.

In Isaiah,

Come down and sit on the dust, O virgin daughter of Babel; sit on the ground. Sit in silence, and go into darkness, O daughter of the Chaldeans. She says in her heart, A widow I shall not sit. Isaiah 47:1, 5, 8.

Similar uses of the word occur elsewhere, such as sitting in darkness, Isaiah 42:7; sitting in council and sitting alone, Jeremiah 15:7; sitting on the right hand and on the left, Matthew 20:21, which stands for remaining in a state of power over others; and sitting on the right hand of God's power, Matthew 26:63-64; Mark 16:19, which refers to the Lord and stands for Divine almighty power that will remain forever.
