A.T. Robertson Commentary Luke 12:11

"And when they bring you before the synagogues, and the rulers, and the authorities, be not anxious how or what ye shall answer, or what ye shall say:" — Luke 12:11 (ASV)

Be not anxious (μη μεριμνησητε). First aorist active subjunctive with μη in prohibition. Do not become anxious. See a similar command to the Twelve on their Galilean tour (Matthew 10:19f.) and in the great discourse on the Mount of Olives at the end (Luke 21:14f.), given twice by Luke as we see.

How or what ye shall answer (πως η τ απολογησησθε). Indirect question and retaining the deliberative subjunctive απολογησησθε and also ειπητε (say).
