'Part' in the Bible

So I looked, and behold, an ashen (pale greenish gray) horse [like a corpse, representing death and pestilence]; and its rider’s name was Death; and Hades (the realm of the dead) was following with him. They were given authority and power over a fourth part of the earth, to kill with the sword and with famine and with plague (pestilence, disease) and by the wild beasts of the earth.

The first [angel] sounded [his trumpet], and there was [a storm of] hail and fire, mixed with blood, and it was hurled to the earth; and a third of the earth was burned up, and a third of the trees were burned up, and all the green grass was burned up.

The name of the star is Wormwood; and a third of the waters became wormwood, and many people died from the waters, because they had become bitter (toxic).

Blessed (happy, prosperous, to be admired) and holy is the person who takes part in the first resurrection; over these the second death [which is eternal separation from God, the lake of fire] has no power or authority, but they will be priests of God and of Christ and they will reign with Him a thousand years.

But as for the cowards and unbelieving and abominable [who are devoid of character and personal integrity and practice or tolerate immorality], and murderers, and sorcerers [with intoxicating drugs], and idolaters and occultists [who practice and teach false religions], and all the liars [who knowingly deceive and twist truth], their part will be in the lake that blazes with fire and brimstone, which is the second death.”
