John Gill 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)

And when they bring you to the synagogues
Of the Jews, to be examined and scourged by the rulers of them:

and to magistrates and powers ;
Heathen ones; the Persic version reads, "princes and kings"; and the Ethiopic version, "princes, kings, and judges"; see (Matthew 10:18)

Take you no thought how, or what thing you will answer, or what you
will say ;
be not anxiously concerned, neither about the manner, nor the matter of your answer, apology, and defence: in the first part of this clause, the Syriac, Persic, and Ethiopic versions, only read, "how"; and the Arabic version only, "what"; (See Gill on Matthew 10:19).
