Table with two customer IDs that I want to relate to the entity

Let's say I have a transaction where Party1 and Party2 are associated, eg by a transaction - let's say Party1 sells something to Party2. I have a list of transaction IDs, eg transaction1 is Party1 sells goods to Party2, transaction2 is Party3 sells goods to Party4 and so on. I have another table, Entities, that tells me that Party1 is 'Smith Enterprises' and Party2 is 'Jones Corp' etc. I want to create a query where Access puts the name of the party in for both parties, eg the transaction now says 'Smith Enterprises' sells goods to 'Jones Corp'. I can't figure out how to get a query to look up Party1 and Party2 in Entities and insert the entity name for both. I can do them one at a time and create a list of identified sellers or a list of identified buyers, then join them back together, but I feel sure there must be a more efficient way of doing this. Apologies if this is either a trivial request or unclear; I'm a 'semi-competent amateur' trying to help myself in the absence of organisational coding resources. But if you tell me which command(s) I need to use, I can probably figure it out from tutorials.
