Matching numbers from multiple columns

[theangnat]

I have column A which is a subset of IDs, Column B which is the full list of IDs, and column C which is the full list of names attached to the IDs. I need to delete the extra IDs (the ones that are not in the subset in Column A) from column B and the corresponding names from column C whilst maintaining the subset of IDs from column A. Put simply, I need to delete both rows in Column B and C if the ID is not in column A. Make sense? Looked around for how to do this and got close but couldn't figure it out completely.
