Gethsemane is a metaphorical location of pain and suffering, it indicates and aggrandises the true meaning of suffering. Gethsemane is a place of weeping but also preparation for what will come ( pain). Gethsemane is where christ weep and prayed that the cup, his cup of suffering will elude him, he hoped that the hammer of pain will be stopped before it lands. He realized that he couldn't avoid what was coming  "the death on the cross". A death he didn't deserve but was more than willing to pay for.
