9737. 'When it is carried' means bringing into being and keeping in being. This is clear from the meaning of 'carrying' as holding in a state of goodness and truth, thus bringing into being and keeping in being, dealt with in 9500. 'Carrying' has a similar meaning in Isaiah,

Hearken to Me, O house of Jacob, and all the remnant of the house of Israel who have been carried from the womb. Even to [your] old age I am the Same, and even to grey hair I will carry [you]; I have made, and I will carry, and I will bear. Isaiah 46:3-4.

Here 'making' stands for, that it may come into being; 'carrying', that it may continue in being; and 'bearing', that it may unceasingly go on coming into being.

'Twenty,' when referring to a quantity, signifies everything, or fullness, because it is ten twice. In Genesis 18:31, 'twenty', like all numbers occurring in the Word, signifies things and states. The significance of 'twenty' can be seen in its factors, namely, ten and two.

In the Word, 'Ten,' and 'tenths,' signify remains, i.e. every good and truth which the Lord puts into a person from infancy to the end of life.

'Ten twice,' 'two tenths,' and 'twenty' signify the same thing, but in a higher degree, namely, good. Good things in triplicate signify remains, namely, the good of infancy, the good of ignorance, and the good of intelligence.
