332. And the sun became as black as sackcloth of hair, and the moon became like blood. This symbolically means that all goodness of love was adulterated in those people, and every truth of faith falsified.

The sun symbolizes the Lord in respect to His Divine love, and thus the goodness of love emanating from Him; and in an opposite sense it symbolizes the Lord's Divinity denied, and thus the goodness of love adulterated. See no. 53 above. And because the sun symbolizes the goodness of love, therefore the moon symbolizes the truth of faith. For the sun has a reddish glow owing to its fire, while the moon glows white from the light radiating from the sun, and fire symbolizes the goodness of love, while light symbolizes the truth arising from that goodness. Regarding the moon, see also the places cited above in no. 53.

The sun is said to have become as black as sackcloth of hair because good adulterated is, in itself, evil, and evil is black.

The moon is said to have become like blood because blood symbolizes Divine truth, and in an opposite sense Divine truth falsified. See nos. 379, 684 below.

The sun and moon are described in almost the same way in Joel:

The sun shall be turned into darkness, and the moon into blood, before the coming of the great and terrible day of Jehovah. (Joel 2:31)

7891. 'And on the first day there shall be a holy convocation' means that at the beginning all must be together. This is clear from the meaning of 'the first day' as the beginning, that is to say, of the deliverance from those who have molested, and so from damnation; and from the meaning of 'a holy convocation' as the regulation that all must be together. The people were called to convocations in order that the whole of Israel might be assembled together and so represent heaven; for all were divided into tribes, tribes into families, and families into households. Regarding the representation of heaven and the communities there by the tribes, families, and households of the children of Israel, see 7836. Here was the reason why those convocations were called 'holy' and were held at each feast, Leviticus 23:27, 36; Numbers 28:26; 29:1, 7, 12. And the feasts themselves were consequently called 'holy convocations', for all male persons were commanded to be present at them. The fact that the feasts were referred to as 'holy convocations' is clear in Moses,

These are the appointed feasts of Jehovah, which you shall call holy convocations, to present a fire-offering to Jehovah. Leviticus 23:37.

The fact that all male persons were to be present on those occasions is clear in the same author,

Three times in the year all your male persons shall appear before Jehovah your God in the place which He will have chosen - at the feast of unleavened bread, at the feast of weeks, and at the feast of tabernacles. Deuteronomy 16:16.
