This passage is often misinterpreted as a blanket prohibition against any preparation for speaking or teaching, such as sermons or evangelism, implying believers should wing it spontaneously in all situations, which ignores broader biblical calls to study and readiness like in 2 Timothy 2:15; it is specifically for persecution trials where lives are at stake and divine intervention is promised, not routine ministry or casual conversations.
Matthew 10:19
King James Version (1769)
19 But when they deliver you up, take no thought how or what ye shall speak: for it shall be given you in that same hour what ye shall speak.
Jesus assures his disciples that when they are arrested and brought before governors and kings for his sake, they need not worry about preparing a defense or what to say, because in that very hour, the Spirit of their Father will supply the right words, teaching reliance on God's timely guidance and empowerment amid persecution rather than human wisdom alone.
