A.T. Robertson Commentary 2 Thessalonians 3:16

"Now the Lord of peace himself give you peace at all times in all ways. The Lord be with you all." — 2 Thessalonians 3:16 (ASV)

The Lord of peace himself (αυτος ο κυριος της ειρηνης). See 1 Thessalonians 5:23 for

the God of peace himself .

Give you peace (δοιη υμιν την ειρηνην). Second aorist active optative (Koine) of διδωμ, not δωη (subjunctive). So also Ro 15:5; 2 Timothy 1:16,18. The Lord Jesus whose characteristic is peace, can alone give real peace to the heart and to the world. (John 14:27).
