John 6:4BSB·traditional attribution

Now the Jewish Feast of the Passover was near.

Matthew Henry Presbyterian @wholebiblehenry

We have here an account of Christ's feeding five thousand men with five loaves and two fishes, which miracle is in this respect remarkable, that it is the only passage of the actions of Christ's life that is recorded by all the four evangelists.

Commenting on John 6:1-14

John Gill Reformed Baptist @doctorgill

And the passover, a feast of the Jews, was nigh. This was the third passover, since our Lord's baptism, and entrance on his public ministry; see Joh 2:13. Whether Christ went up to this feast is not certain; some think he did not; but from what is said in Joh 7:1, it looks as if he did: how nigh it was to the feast, cannot well be said.

Albert Barnes Presbyterian @notesbybarnes

Verse 4. The passover. . A feast of the Jews. This is one of the circumstances of explanation thrown in by John which show that he wrote for those who were unacquainted with Jewish customs.
