'Agony' in the Bible

“Now My soul is troubled and deeply distressed; what shall I say? ‘Father, save Me from this hour [of trial and agony]’? But it is for this [very] purpose that I have come to this hour [this time and place].

When a woman is in labor she has pain, because her time has come. Yet when she has given birth to her child, she doesn't remember the agony anymore because of the joy of having brought a human being into the world.
