Charles Ellicott Commentary Matthew 10:19

"But when they deliver you up, be not anxious how or what ye shall speak: for it shall be given you in that hour what ye shall speak." — Matthew 10:19 (ASV)

Take no thought — This is meant in the same sense as in Matthew 6:25: “Do not be over-anxious in that moment.” These words indicate an almost tender sympathy for the feelings of the Galilean disciples, who were “unlearned and ignorant men” standing before those considered their superiors in power and knowledge. The words that follow contain a two-fold promise: not only what they should say, but also how they should say it—the very form and phrasing—would be given to them in that hour. The courage of Peter and John before the Sanhedrin is at once the earliest and most striking instance of this promise’s fulfillment (Acts 4:13).
