A.T. Robertson Commentary Ephesians 6:19

"And on my behalf, that utterance may be given unto me in opening my mouth, to make known with boldness the mystery of the gospel," — Ephesians 6:19 (ASV)

That utterance may be given unto me (ινα μο δοθη λογος). Final clause with ινα and first aorist passive subjunctive of διδωμ, to give. See a like request in Col 4:3. Paul wishes their prayer for courage for himself.
