How do Biblical Unitarians explain the use of the singular in 2 Thessalonians 2:16-17?

2 Thessalonians 2:16-17 is > "16 Now may our Lord Jesus Christ Himself and God our Father, who by > grace has loved us and given us eternal comfort and good hope, > 17 encourage your hearts and strengthen you in every good word and deed." (Berean Standard Bible) This seems a bit strange, as St. Paul is mentioning Jesus **and** the Father, but then uses singular verbs at 17. One explanation of this sometimes given by Trinitarians is that St. Paul is gesturing toward the Trinitarian nature of God with this grammatical usage. How do Biblical Unitarians understand Paul's grammar at 2 Thessalonians 2:16-17?
