What is virgil's advice to dante as spoken at the gate of hell?

When Dante and Virgil encounter the Gate of Hell, they find the inscription summarized to "Abandon all hope, those who enter here". Dante is apprehensive about entering Hell in fear of losing hope, and remaining trapped. Virgil assures him that he is safe in his travel, but gives the advice to leave behind any fears or doubts when entering Hell because the suffering is divine justice for those in Hell. He gives the advice to have faith in the justice applied here, and to learn from the fates of those in Hell.
