Arcana Coelestia # 7201
7201. 'Therefore say to the children of Israel' means that the law of God will enable those who belong to the Lord's spiritual kingdom to discern. This is clear from the representation of Moses, the one who is told to 'say to the children of Israel', as the law of God, dealt with in 6723, 6752; from the meaning of 'saying' as discerning, dealt with in 1791, 1815, 1819, 1822, 1898, 1919, 2080, 2506, 2515, 2619, as enabling to discern, since the command 'say' has reference to the law of God; and from the representation of 'the children of Israel' as those who belong to the Lord's spiritual kingdom, dealt with in 6426, 6677.
Matthew 17:10-13
10
His disciples asked him, saying, "Then why do the scribes say that Elijah must come first?"
11
Jesus answered them, "Elijah indeed comes first, and will restore all things,
12
but I tell you that Elijah has come already, and they didn't recognize him, but did to him whatever they wanted to. Even so the Son of Man will also suffer by them."
13
Then the disciples understood that he spoke to them of John the Baptizer.
