This is the second: ‘You shall [unselfishly] love your neighbor as yourself.’ There is no other commandment greater than these.”

Immediately a rooster crowed the second time. And Peter remembered what Jesus said to him: “Before a rooster crows twice, you will deny Me three times.” And thinking of this, he began weeping [in anguish].
