John Gill Commentary John 21:10

"Jesus saith unto them, Bring of the fish which ye have now taken." — John 21:10 (ASV)

Jesus says to them
The disciples:

bring of the fish which you have now caught :
for they might have caught some before, though so few and small, as scarcely to be reckoned any; nor were they bidden to bring all they had taken, only some of them, to add to these Christ had prepared for them on land; they being both indeed of a miraculous production, and the effects of his divine power. Christ's view in ordering to bring some of them, and put to those that lay upon the coals, was partly that they might have enough to make a meal of for them all; and also, that they might have a more perfect knowledge of the miracle wrought, by seeing the number and largeness of the fishes, and by bringing the net full of them to shore unbroken;

and may be an emblem of the bringing of souls to Christ by the ministry of the word, thereby adding to those that are already gathered.
