What is Virgil's advice to Dante at the Gate of Hell?

Virgil tells Dante that he has to stop being
scared and put aside any lack of belief. He has to accept that what he sees inside Hell is what
is meant to happen by the will of God.

Dante is frightened when he sees the
sign on the gates of Hell that ends with, "Abandon All Hope Ye Who Enter Here." The
sign indicates that Hell was created by God; the people suffering inside are getting their
earned reward for their behavior. Dante tells Virgil that he has difficulty understanding
it.

Virgil says:

Here all suspicion
needs must be abandoned,
All cowardice must needs be here extinct.

We to the place have come, where I have told thee
Thou shalt behold the people
dolorous
Who have foregone the good of intellect.

He is explaining to Dante that he must be brave and accept what he sees within. The
people will be miserable and suffering, but that is what is supposed to happen. Virgil then
takes Dante's hand and comforts him as they go in.
