Watchtower, October 1, 1952, pages 596 to 604:

     "Haters of God and his people are to be hated, but this does
not mean that we will take any opportunity of bringing physical
hurt to them in a spirit of malice or spite, for both malice and
spite belong to the Devil, whereas pure hatred does not.  We must
hate in the truest sense, which is to regard with extreme and
active aversion, to consider as loathsome, odious, filthy, to
detest.  Surely any haters of God are not fit to live on his
beautiful earth.  The earth will be rid of the wicked and we shall
not need to lift a finger to cause physical harm to come to them
for God will attend to that, but we must have a proper perspective
of these enemies.  His name signifies recompense to the enemies.

     What do you do with anything loathsome or repugnant that you
detest and abhor?  The answer is simple.  You get away from it or
remove it from your presence.  You do not want to have anything at
all to do with it.  This must be exactly our attitude toward the
haters of Jehovah.  Prophetically it is written:  'Surely thou wilt
slay the wicked, O God: depart from me therefore, ye bloodthirsty
men.  For they speak against the wickedly, and thine enemies take
thy name in vain.  Do not I hate them, O Jehovah, that hate thee? 
I hate them with perfect hatred.' (Ps. 139:19-22, AS)  Bloodthirsty
men are shedders of blood, and therefore guilty men.  We hold their
conduct in complete abhorrence.  Think about the awful treatment
meted out to our brothers in Germany, Greece and Poland during
World War II and since, by reason of the ferocity and beastliness
of the totalitarian organization, whereby thousands were killed by
those bloodthirsty creatures!  Their motives, opposition to Jehovah
and his people, their perfidy and wicked idolatrous purposes we
perfectly abhor.  With them we have neither part, interest nor
affection.

     Jehovah's enemies are recognized by their intense dislike for
his people.  For they would break it down and have all of Jehovah's
witnesses sentenced to jail or concentration camps if they could. 
Not because they have anything against the witnesses personally,
but on account of their work.  They publish blasphemous lies and
reproach the holy name Jehovah.  Do we not hate those who hate God?
We cannot love those hateful enemies, for they are fit only for
destruction.  We utter the prayer of the psalmist:  'How long, O
God, shall the adversary reproach?  Shall the enemy blaspheme thy
name for ever?  Why drawest thou back thy hand, even thy right
rand?  Pluck it out of thy bosom and consume them.' (Ps. 74:10, 11,
AS)  We pray with intensity and cry out this prayer for Jehovah to
delay no longer, and plead that his anger be made manifest.  Bring
forth your arm and let the enemies see it, and use it for their
hurt and destruction.  Surely the time is now ripe, the iniquity
ofJehovah's enemies has come to the full.  Surely we all say, 'O
Jehovah, do not hold back your punishment of the wicked.  Pluck
your hand out and use it to let the enemies know your name!  Exert
your power again, for with one blow from your arm the enemies would
disappear!'"
