3104. 'Half a shekel in weight' means the amount needed for the introduction. This is clear from the meaning of 'a shekel', 'half a shekel', and 'weight'. 'A shekel' means the price or valuation of good and truth, and 'half a shekel' a defined amount of it, see 2959. 'Weight' means the state of something as regards good, as will be seen [below]. From these considerations it is evident that 'half a shekel in weight' means and embodies the amount as regards the good which 'a gold nose-jewel' is used to mean - that amount being the quantity of it that was needed for the introduction, as is plain from what comes before and after this point in the story.
 That 'weight' is the state of something as regards good is evident from the following places in the Word: In Ezekiel where the prophet was told to eat food each day twenty shekels in weight, and to drink water in measure the sixth of a hin,
For, behold, I am breaking the staff of bread in Jerusalem, so that they may eat bread by weight and with anxiety, and drink water by measure and with dismay; that they may be in want of bread and water. Ezek 4:10, 11, 16, 17.
This refers to the vastation of good and truth, which is represented by 'the prophet'. A state of good when vastated is meant by their having to eat food and bread 'by weight', and a state of truth when vastated by their having to drink water 'by measure' - 'bread' meaning that which is celestial, and so good, see 276, 680, 2165, 2177, and 'water' that which is spiritual, and so truth, 739, 2702, 3058. From this it is evident that 'weight' is used in reference to good, and 'measure' to truth.
 In the same prophet,
You shall have just balances, and a just ephah, and a just bath. Ezek 45:10and following verses.
This refers to the holy land, by which the Lord's kingdom in heaven is meant, as may be recognized from every detail at this point in this prophet, where what are required are not balances, an ephah, and a bath that are just but the goods and truths meant by those weights and measures. In Isaiah,
Who has measured the waters in the hollow of His hand and weighed the heavens in [His] palm, and gathered the dust of the earth in a measure, and weighed the mountains in a balance, and the hills in the scales? Isa 40:12.
'Weighing the mountains in a balance and the hills in the scares' stands for the truth that the Lord is the source of the heavenly things of love and charity, and that He alone orders the states of these things. For 'the mountains' and 'the hills' referred to in connection with those weights mean the heavenly things of love, see 795, 796, 1430, 2722.
 In Daniel,
The writing on the wall of Belshazzar's palace was, Mene, Mene, Tekel, Upharsin. This is the interpretation: Mene, God has numbered your kingdom and brought it to an end; Tekel, you have been weighed in the scales and have been found wanting; Peres, your kingdom has been divided and given to the Medes and Persians. Dan 5:25-28.
Here 'mene' or 'He has numbered' has reference to truth, but 'tekel' or 'weighed in the scales' to good. Described in the internal sense is the time when the age is drawing to a close.
