{Didymus} (Didumos). The word means twin. Clearly Thomas
had a twin brother or sister. Applied two other times to him
( 20:24  21:2 ). The Aramaic word for Thomas means Twin and
Didymus is just the Greek equivalent of Thomas. He may even in
Greek circles have been called Didymus. {His fellow disciples}
(	ois sunmath(8874)ais). Dative case and article use like "his."
Only use of sunmath(8874)es in the N.T., rare word (in Plato). {Us
also} (kai h(886d)eis). As well as Jesus, since he is bent on
going. {That we may die with him} (hina apothan(936d)en met'
autou). Purpose clause with hina and the second aorist active
subjunctive of apothn(8873)k(935c). Die with Jesus, Thomas means.
Lazarus is already dead and they will kill Jesus (verse  8 ).
Pessimistic courage surely.
