'Buy' in the Bible

Ye shall buy of them food for money, that ye may eat; and water shall ye also buy 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 again no more; and there ye shall be sold unto your enemies for bondmen and bondwomen, and there shall be no man to buy you.
