the tunic: the plain inner garment worn next to the skin, under the outer cloak
The tunic was the shirt of the ancient Mediterranean world, the simple garment worn directly against the skin. Over it a person put on the cloak, the heavier outer wrap. Together the two made up an ordinary outfit, and the pair turns up again and again, in a laundry list, a dowry, or a plain description of what someone had on. A person of modest means owned two tunics, one to wear and one in reserve; the very poor had only one.
Because it is the everyday layer worn close to the body, the word does quiet work throughout the New Testament. When Jesus tells a disciple who is sued in court to hand over the tunic and then the cloak as well (Matthew 5:40), the force of the saying is that the cloak was legally protected as a poor person's covering for the night, so giving up both leaves the person with nothing. When John the Baptist tells whoever has two tunics to share with someone who has none (Luke 3:11), the spare tunic stands for the smallest surplus a person can give away. When Jesus sends the disciples out with no spare tunic (Mark 6:9; Matthew 10:10; Luke 9:3), he strips them of the traveler's normal kit and leaves them dependent on the hospitality of others.
In the plural the word can widen to mean clothing in general. That is how most scholars read the moment when the high priest tears his tunics at Jesus' trial (Mark 14:63): these are his ordinary clothes at a night hearing, not the sacred robes kept in the temple. And because the tunic is what touches the skin, Jude can speak of hating even the tunic stained by the flesh (Jude 1:23), an image of defilement so intimate it reaches the innermost layer.
The most discussed tunic in the New Testament is the seamless one the soldiers refused to tear at the cross (John 19:23). Woven in one piece rather than sewn together, it was a costly item, and readers from the earliest centuries on have wondered whether John wants us to hear an echo of the high priest's robe, or to see a picture of a people that cannot be divided. Those readings are old and appealing, but they remain far from settled.
Nuances
Whether the seamless, one-piece tunic of John 19:23 is meant to carry symbolic weight, and if so what kind.
- contestedThe detail is a narrative mechanism: it explains why the soldiers cast lots for this garment instead of dividing it, so that the scene fulfills Psalm 22:18, and it carries no further symbolism, since the Gospel of John presents no high-priestly picture of Jesus anywhere else.; C.

- minorityThe one-piece woven tunic deliberately echoes the high priest's robe, which Josephus (Antiquities 3.161) describes as woven of a single piece rather than stitched, so that Jesus dies clothed as the true high priest.; J.
