Literary term for referring to a future event in the story line

Is there a literary term for when an author refers to something that is going to happen later?

I am referring to two usages of this technique.

The first is when an author says "as will be explained later" or some variation there-of.

The second, which I am more interested in, is when the author says "before XYZ changed all of that" when XYZ is something that happens later in the story.

An example of the second usage is in Genesis 13:10, which refers to the destruction of Sodom before it occurs.

Solution 1:

The term foreshadowing often is used in this context. From en.wiktionary, it means “A literary device in which an author drops subtle hints about plot developments to come later in the story”.

If the hints are less than subtle – as in Genesis 13:10, which parenthetically remarks, “This was before the LORD destroyed Sodom and Gomorrah” – one might refer, somewhat oxymoronically, to blatant foreshadowing, or perhaps premature dénouement.

Terms that suggest unsubtle foreshadowing include announcing (“To give public notice, or first notice of; to make known; to publish; to proclaim”), annunciating (“To announce”), and prefiguring (“To show or suggest ahead of time; to represent beforehand (often used in a Biblical context)”).

Terms more akin to foreshadowing include presage, portend, and perhaps augur.
