José Saramago said this quote

Holding the lamb in his arms, Jesus watched the people file past, some coming, some going, some carrying animals to be sacrificed, some returning without them, looking joyful and exclaiming, Alleluia, Hosanna, Amen, or saying none of these things, feeling it was inappropriate to walk around shouting Hallelujah or Hip hip hurrah, because there is really not much difference between the two expressions, we use them enthusiastically until with the passage of time and by dint of repetition we finally ask ourselves, What does it mean, only to find there is no answer.
