How does the author use foreshadowing in The Scarlet Letter?

Examples of foreshadowing in The Scarlet Letter:

"But on one side of the portal, and rooted almost at the threshold, was a wild rose-bush, covered, in this month of June, with its delicate gems, which might be imagined to offer their fragrance and fragile beauty to the prisoner as he went in, and to the condemned criminal as he came forth to his doom, in token that the deep heart of Nature could pity and be kind to him."

Foreshadows beauty and good amonst the ugliness.

"On the breast of her gown, in fine red cloth, surrounded with an elaborate embroidery and fantastic flourishes of gold thread, appeared the letter A. It was so artistically done, and with so much fertility and gorgeous luxuriance of fancy, that it had all the effect of a last and fitting decoration to the apparel which she wore, and which was of a splendour in accordance with the taste of the age, but greatly beyond what was allowed by the sumptuary regulations of the colony."

This quote foreshadows Hester's individuality and lack of shame.

“Why dost thou smile so at me?” inquired Hester, troubled at the expression of his eyes. “Art thou like the Black Man that haunts the forest round about us? Hast thou enticed me into a bond that will prove the ruin of my soul?”
“Not thy soul,” he answered, with another smile. “No, not thine!”

This quote foreshadows Chillingworth's revenge against Pearl's father.
