John 20:24

But Thomas, one of the twelve, called Didymus
The person here spoken of, is described by his Hebrew name Thomas, and his Greek one Didymus, which both signify a twin; and perhaps he was one. It was common with the Jews to have two names, a Jewish and a Gentile one; by the one they went in the land of Israel, and by the other when without the land ^F17; nay, they often went by one name in Judea, and by another in Galilee ^F18; where Thomas might go by the name of Didymus with the Greeks, that might live with the Jews in some of those parts: he is also said to be "one of the twelve" apostles, which was their number at first, though Judas now was gone off from them, and therefore are sometimes only called the "eleven"; but this having been their complement, it is still retained; but what is observed of him to his disadvantage and discredit is, that he

was not with them when Jesus came:
Beza's ancient copy reads, "he was not there with them"; and so read the Syriac, Arabic, and Persic versions; he either had not returned to the rest after their scattering one from another upon the apprehending of Christ; or did not choose to assemble with the rest, for fear of the Jews; or was taken up with some business and affair of life; however, he was not with the rest of the disciples, when they were assembled together, and Jesus appeared among them: as it is of good consequence to attend the assemblies of Christ's disciples and followers, so it is of bad consequence to neglect or forsake them: it is frequently to good purpose that persons attend them; here God comes and blesses his people, Jesus grants his presence, the graces of the Spirit are increased, and drawn forth into exercise; souls that have lost sight of Christ find him, disconsolate ones are comforted, weak ones strengthened, and hungry ones fed: on the other hand, not to attend is of bad consequence; neglect of assembling together exposes to many snares and temptations; brings on a spiritual leanness; leads to an indifference and lukewarmness: issues in a low degree of grace, and a non-exercise of it, and in a loss of Christ's presence.
