Redeemed!

The word, redeem appears 41 times in Blake's poetry; for him 'redeem' had several meanings, especially the way it's commonly used or the ironic sense that was so familiar to him:

Spring like redeemed captives, common.

The State namd Satan never can be redeemd in all Eternity, ironic.

His myth speaks of three kinds of men:

from Plates 6 and 7 of Milton:
Here the Three Classes of Mortal Men take their fixd destinations
And hence they overspread the Nations of the whole Earth & hence
The Web of Life is woven: & the tender sinews of life created
And the Three Classes of Men regulated by Los's hammer.

PLATE 7:

The first, The Elect from before the foundation of the World:
The second, The Redeem'd. The Third, The Reprobate & form'd
To destruction from the mothers womb:
The morning comes, the night decays, the watchmen leave their
stations;
The grave is burst, the spices shed, the linen wrapped up;
The bones of death, the cov'ring clay, the sinews shrunk & dry'd.
Reviving shake, inspiring move, breathing! awakening!

from AMERICA a PROPHECY
Printed by William Blake in the year 1793.
Let the slave grinding at the mill, run out into the field:
Let him look up into the heavens & laugh in the bright air;
Let the inchained soul shut up in darkness and in sighing,
Whose face has never seen a smile in thirty weary years;
Rise and look out, his chains are loose, his dungeon doors are
open.
And let his wife and children return from the opressors scourge;
They look behind at every step & believe it is a dream.
Singing. The Sun has left his blackness, & has found a fresher
morning
And the fair Moon rejoices in the clear & cloudless night;
For Empire is no more, and now the Lion & Wolf shall cease.

From the Four Zoas, Night 7:
The Spectre of Urthona wept before Los Saying I am the cause
That this dire state commences I began the dreadful state
Of Separation & on my dark head the curse & punishment
Must fall unless a way be found to Ransom & Redeem
But I have thee my [Counterpart Vegetating] miraculous
These Spectres have no [Counter(parts)] therefore 
they ravin
Without the food of life Let us Create them Coun[terparts]
For without a Created body the Spectre is Eternal Death
Los trembling answerd Now I feel the weight of stern repentance
Tremble not so my Enitharmon at the awful gates
Of thy poor broken Heart I see thee like a shadow withering
As on the outside of Existence but look! behold! take comfort!
Turn inwardly thine Eyes & there behold the Lamb of God
Clothed in Luvahs robes of blood descending to redeem
(Erdman 369)

PLATE 5 of Milton: 
 Palamabron with the fiery Harrow in morning returning
From breathing fields. Satan fainted beneath the artillery
Christ took on Sin in the Virgins Womb, & put it off on the Cross
All pitied the piteous & was wrath with the wrathful & Los heard
it.
There is a State namd Satan learn distinct to know O Rahab
The Difference between States & Individuals of those States
The State namd Satan never can be redeemd in all Eternity
But when Luvah in Orc became a Serpent he des[c]ended into
That State calld Satan Enitharmon breathd forth on the Winds
Of Golgonooza her well beloved knowing he was Orc's human remains
She tenderly lovd him above all his brethren he grew up
In mothers tenderness The Enormous worlds rolling in Urizens
power
Must have given Satan by these mild arts Dominion over all
(Erdman 380-81)
