The residue - The remainder. Those who remained at Jerusalem.

And they went and told it unto the residue,.... Upon their return to Jerusalem, which was on the same night, they went to the eleven apostles, and the other disciples that were with them, and related the whole affair to them; how that Jesus had joined them by the way, and discoursed much with them about himself, and expounded the Scriptures on the road; and when they came to the end of their journey, sat down at meat with them, when he was very plainly discerned, and known by them, and then disappeared; see Luke 24:33;
neither believed they them. "These two", as the Arabic version reads; though they were men, and fellow disciples; and this was a repeated testimony, and a second set of witnesses of Christ's resurrection to them; all which aggravates their unbelief: upon sight of them they said, "the Lord is risen indeed, and hath appeared to Simon", Luke 24:34; the reason of which Dr. Lightfoot thinks was this, that Peter hearing that Christ was risen, and went before them into Galilee, was eager to see him, and therefore took this journey along with Cleophas, which the rest of the disciples knew; and he returning so soon, they concluded he had seen him: but when he, and Cleophas, told the whole affair, they were as unbelieving as ever.

they went and told it unto the residue: neither believed they them, &c.

And they went. Back to Jerusalem, to the upper room where the ten disciples were assembled (Luke 24:33).
And told it. They related their whole interesting interview.

Neither believed they them - They were moved a little by the testimony of these, added to that of St. Peter, Luke 24:34; but they did not yet fully believe it.
