Yaakov ben Asher

“ Be brazen as a leopard, light as an eagle, swift as a deer and strong as a lion to do the will of your Father in heaven." - Four specific aspects are mentioned of serving one's creator. He starts with be "brazen as a leopard", because this concept is a fundamental principle of serving the Creator. ”

“ So too does it apply to the issue of shame, as sometimes a person is ashamed of people more than one is ashamed of the Creator, Blessed Be He; therefore he admonishes you to brace yourself against the mockers and be not ashamed. ”
