'Buy' in the Bible

For his disciples were gone away into the city to buy food.

Jesus therefore lifting up his eyes, and seeing that a great multitude cometh unto him, saith unto Philip, Whence are we to buy bread, that these may eat?

For some thought, because Judas had the bag, that Jesus said unto him, Buy what things we have need of for the feast; or, that he should give something to the poor.
