Lookup Value In Array - Where Found Multiple Times Return Closest Prior Date

I have a list of ID Numbers and Dates. Let's call this "List 1".

I also have a second list "List 2" which also contains a list of ID Numbers and Dates as well as a third column for Rating.

I am trying to extract the Rating for each ID Number from List 2 and display in List 1. The problem is that the Rating can change with time, so List 2 contains several different Date and Rating values for the same ID Number.

What I need to do is lookup the ID Number from List 1 and return from List 2, for that ID Number, the Rating at the closest date prior to the date for that ID Number in List 1. Example below:

List 1
List 2

ID Number
Date
Rating

111
17/04/13
5
