John Gill Commentary Luke 5:9

"For he was amazed, and all that were with him, at the draught of the fishes which they had taken;" — Luke 5:9 (ASV)

Far he was astonished, and all that were with him
His brother Andrew, and the servants they had with them to manage the vessel, and cast the nets:

at the draught of the fishes they had taken ;
being so large and numerous, as the like was never seen, nor known by them before.
