Besides Romeo and Juliet dying in Shakespeare's Romeo and Juliet how does this scene show foreshadowing

Romeo: “Amen, amen. But come what sorrow can,/ It cannot countervail the exchange of joy/That one short minute gives me in her sight./Then love-devouring death do what he dare;/ It is enough I may but call her mine”. (Act 2 Scene 6, Lines 3 - 8)
