Children - A term of affection and friendship, 1-John 2:18.
Any meat - This word (Greek) means anything eaten with bread. It was used by the Greeks especially to denote fish (Schleusner).

Children - Παιδια, a term of familiarity and affectionate kindness: it is the vocative case plural of παιδιον, which is the diminutive of παις, and literally signifies little children, or beloved children. How the margin has made sirs out of it I cannot conceive.
Any meat - Προσφαγιον from προς, besides, and φαγω, I eat; any thing that is eaten with bread, or such like solid substances, to make the deglutition the more easy: here it evidently means any kind of fish; and our Lord seems to have appeared at first in the character of a person who wished to purchase a part of what they had caught: see the note on John 6:9.

Then Jesus saith unto them, children,.... And still they knew him not, though he used this endearing and familiar appellation, and which they had been wont to hear from him; and he had called them by a little before his departure from them, John 13:33 and which he uses here as expressive of his tender affection for them, their relation to him, and that he might be known by them:
have ye any meat? that is, as the Syriac renders it, , "anything to eat"; meaning fish that they had caught; and whether they had got a sufficient quantity to make a meal of for him and them.
They answered him no; they had got nothing at all; or at least what they had was far from being enough to make a breakfast of; for so a meal early in a morning may be most properly called, though it is afterwards called dining. Christ's children, true believers, are sometimes without spiritual food; there is always indeed enough in Christ, and he has an heart to give it; but either through prevailing iniquity they feed on something else, or do not go to him for food, or go elsewhere; but he will not suffer them to starve; for as he has made provisions for them in the ministry of the word and ordinances; and he himself is the bread of life; if they do not ask him for food, he will ask them whether they have any; will kindly invite them to the provisions he himself makes; will bid them welcome, and bless them to them.

Children--This term would not necessarily identify Him, being not unusual from any superior; but when they did recognize Him, they would feel it sweetly like Himself.
have ye any meat?--provisions, supplies, meaning fish.
They answered . . . No--This was in His wonted style, making them tell their case, and so the better prepare them for what was coming.
