Aeneid 8.169–171

Ergo et quam petitis iuncta est mihi foedere dextra,

et lux cum primum terris se crastina reddet,

auxilio laetos dimittam opibusque iuvabo.

So my right hand, which you seek, is joined to yours in covenant,

and as soon as tomorrow's light returns to the earth,

I will send you on your way rejoicing in my support and help you with my resources.
