Resurrection, the first
'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

1260. Since 'nations' in the Most Ancient Church and in the Ancient Church meant goods or good persons, therefore also in the contrary sense they mean evils or evil persons Similarly with 'peoples'; since these meant truths, therefore also in the contrary sense they mean falsities. For in a corrupted Church good is turned into evil, and truth into falsity, as a consequence of which the meaning of nations and peoples in that contrary sense occurs many times in the Word, as in Isaiah 13:4; 14:6; 18:2, 7; 30:28; 34:1-2; Ezekiel 20:13; and in many other places.
