'Sold' in the Bible

And if thy brother, an Hebrew man, or an Hebrew woman, be sold unto thee, and serve thee six years; then in the seventh year thou shalt let him go free from thee.

And the LORD shall bring thee into Egypt again with ships, by the way whereof I spake unto thee, Thou shalt see it no more again: and there ye shall be sold unto your enemies for bondmen and bondwomen, and no man shall buy you.

How should one chase a thousand, and two put ten thousand to flight, except their Rock had sold them, and the LORD had shut them up?
