Albert Barnes Commentary Mark 6:30

"And the apostles gather themselves together unto Jesus; and they told him all things, whatsoever they had done, and whatsoever they had taught." — Mark 6:30 (ASV)

And the apostles gathered themselves together. That is, those whom he had sent out two and two (Mark 6:7). Having travelled around the country, they returned and met the Saviour at Capernaum.
