“And he said unto them, Come ye yourselves apart into a desert place, and rest a while: for there were many coming and going, and they had no leisure so much as to eat.”
Mark 6:31 — Greek Interlinear
Church Fathers on Mark 6:31

Let us also learn, when we are sent on any mission, not to go far away, and not to overstep the bounds of the office committed, but to go often to him, who sends us, and report all that we have done and taught; for we must not only teach but act.
Not only do the Apostles tell the Lord what they themselves had done and taught, but also His own and John’s disciples together tell Him what John had suffered, during the time that they were occupied in teaching, as Matthew relates.
