'Buy' in the Bible

Ye shall purchase food of them for money, that ye may eat; and ye shall also buy water of them for money, that ye may drink.

And Jehovah will bring thee into Egypt again with ships, by the way whereof I said unto thee, Thou shalt see it no more again: and there ye shall sell yourselves unto your enemies for bondmen and for bondwomen, and no man shall buy you.
