'Extra' in the Bible

Don’t take a traveling bag for the road, or an extra shirt, sandals, or a walking stick, for the worker is worthy of his food.

They were to wear sandals, but not put on an extra shirt.

“Take nothing for the road,” He told them, “no walking stick, no traveling bag, no bread, no money; and don’t take an extra shirt.

The next day he took out two denarii, gave them to the innkeeper, and said, ‘Take care of him. When I come back I’ll reimburse you for whatever extra you spend.’
