26. Verse 8 And there was evening, and there was morning, a second day.

What 'evening', 'morning', and 'day' mean, has been shown already at verse 5.

869. (Verse 6) And I saw another angel flying in the midst of heaven. That this signifies manifestation everywhere from the Lord, is evident from the signification of the angel flying in the midst of heaven, as denoting manifestation from the Lord, everywhere. For an angel signifies something from the Lord, because angels are not angels from themselves, but from the Lord; for they are recipients of the Divine truth which proceeds from the Lord; therefore also angels, in the Word, signify Divine truths. Nor is heaven itself heaven from the proprium of the angels, but from the Divine, which is within them; concerning which see above (n. 130, 200, 302). By flying is signified circumspection and presence; concerning which also see above (n. 282); but, here, manifestation, because it manifested the Advent of the Lord, which is meant by having an eternal gospel; and, also, the approach of the Last Judgment. And by in the midst is signified everywhere; concerning which also see above (n. 313). It is therefore evident that by the angel flying in the midst of heaven is signified manifestation everywhere from the Lord.
