Mischna zu Mischlej 21:76

Judah ben Tema said: Be strong as a leopard, and swift as an eagle, and fleet as a gazelle, and brave as a lion, to do the will of your Father who is in heaven. He used to say: the arrogant is headed for Gehinnom and the blushing for the garden of Eden. May it be the will, O Lord our God, that your city be rebuilt speedily in our days and set our portion in the studying of your Torah.
