The lines which contain the element of foreshadowing are: This bodes some strange eruption to our state. He is literally saying that something weird is going to happen to Denmark.
>>>>This bodes some strange eruption to our state.
The word bodes is similar to foreboding. Foreboding is the feeling that something bad is going to happen. This is further stated after the word bodes in the rest of the line when it says "strange eruption to our state." Foreshadowing is a hint for an event or events that will occur later in the story. Here it is foreshadowed that something bad is going to happen.
