'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.

3244. Verses 5-6 And Abraham gave all that he had to Isaac. And to the concubines' sons, whom Abraham had, Abraham gave gifts; and he sent them away from being with Isaac his son - while he was still living - eastwards to the land of the east.

'Abraham gave all that he had to Isaac' in the highest sense means all the Divine things within the Divine Rational, and in the relative sense the celestial things of love imparted to the Lord's celestial kingdom. 'And to the concubines' sons, whom Abraham had, Abraham gave gifts' means that places in the Lord's spiritual kingdom were allotted to those adopted by the Lord's Divine Human, namely those who were spiritual. 'And he sent them away from being with Isaac his son' means the distinguishing and separation of those who were spiritual from those who were celestial. 'While he was still living' means to whom he was able to impart life. 'Eastwards to the land of the east' means towards the good of faith.
