'Tunics' in the Bible

but to wear sandals; and [He told them] not to wear two tunics.

And John replied, “The man who has two tunics is to share with him who has none; and he who has food is to do the same.”

And He said to them, “Take nothing for your journey [that might encumber you]—neither a walking stick, nor bag, nor bread, nor money; and do not even have two tunics apiece.

So Peter got up [at once] and went with them. When he arrived, they brought him into the upstairs room; and all the widows stood beside him, weeping and showing [him] all the tunics and robes that Dorcas used to make while she was with them.
