Luke 12:10-12

Young's Literal Translation

¹⁰ and every one whoever shall say a word to the Son of Man, it shall be forgiven to him, but to him who to the Holy Spirit did speak evil, it shall not be forgiven.

¹¹ `And when they bring you before the synagogues, and the rulers, and the authorities, be not anxious how or what ye may reply, or what ye may say,

¹² for the Holy Spirit shall teach you in that hour what it behoveth [you] to say.'
