Thomas

Boyd’s Bible Dictionary:

(twin). The cautious, susceptible, even doubtful, apostle, whose name, in Greek, was Didymus, “twin,” (Matt. 10:33Philip, and Bartholomew; Thomas, and Matthew the publican; James the son of Alpheus, and Lebbeus, whose surname was Thaddeus; (Matthew 10:3); Mark 3:1818And Andrew, and Philip, and Bartholomew, and Matthew, and Thomas, and James the son of Alpheus, and Thaddeus, and Simon the Canaanite, (Mark 3:18); Luke 6:1515Matthew and Thomas, James the son of Alpheus, and Simon called Zelotes, (Luke 6:15); John 11:16; 14:5-6; 20:24-2916Then said Thomas, which is called Didymus, unto his fellowdisciples, Let us also go, that we may die with him. (John 11:16)
5Thomas saith unto him, Lord, we know not whither thou goest; and how can we know the way? 6Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. (John 14:5‑6)
24But Thomas, one of the twelve, called Didymus, was not with them when Jesus came. 25The other disciples therefore said unto him, We have seen the Lord. But he said unto them, Except I shall see in his hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into his side, I will not believe. 26And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you. 27Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing. 28And Thomas answered and said unto him, My Lord and my God. 29Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed. (John 20:24‑29)
; Acts 1:1313And when they were come in, they went up into an upper room, where abode both Peter, and James, and John, and Andrew, Philip, and Thomas, Bartholomew, and Matthew, James the son of Alpheus, and Simon Zelotes, and Judas the brother of James. (Acts 1:13)).

Concise Bible Dictionary:

One of the twelve apostles, called also DIDYMUS, a twin. He comes prominently before us on two significant occasions: once when he said to the Lord, “We know not whither thou goest, and how can we know the way?” The Lord replied, “I am the way, the truth, and the life” (John 14:5-65Thomas saith unto him, Lord, we know not whither thou goest; and how can we know the way? 6Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. (John 14:5‑6)). Also when he said that he would not believe that the Lord had risen until he had ocular demonstration as to His wounds; but when he saw the Lord, he at once confessed Him as “My Lord and my God” (John 20:19-2919Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, came Jesus and stood in the midst, and saith unto them, Peace be unto you. 20And when he had so said, he showed unto them his hands and his side. Then were the disciples glad, when they saw the Lord. 21Then said Jesus to them again, Peace be unto you: as my Father hath sent me, even so send I you. 22And when he had said this, he breathed on them, and saith unto them, Receive ye the Holy Ghost: 23Whose soever sins ye remit, they are remitted unto them; and whose soever sins ye retain, they are retained. 24But Thomas, one of the twelve, called Didymus, was not with them when Jesus came. 25The other disciples therefore said unto him, We have seen the Lord. But he said unto them, Except I shall see in his hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into his side, I will not believe. 26And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you. 27Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing. 28And Thomas answered and said unto him, My Lord and my God. 29Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed. (John 20:19‑29)). He was not with the other disciples when the Lord breathed into them, and said, “Receive ye the Holy Ghost;” and thus he may be taken as a type of the future remnant of the Jews, who will not believe till they see their Messiah. In contrast to which the Lord added a beautiful sentence respecting those of the present time: “Blessed are they that have not seen, and yet have believed.”
