'Lost' in the Bible

In like manner shalt thou do with his ass; and so shalt thou do with his raiment; and with all lost thing of thy brother's, which he hath lost, and thou hast found, shalt thou do likewise: thou mayest not hide thyself.

And you shall say before the Lord your God, ‘My father [Jacob] was a wandering Aramean, and he [along with his family] went down to Egypt and lived there [as strangers], few in number; but while there he became a great, mighty and populous nation.

For a nation lost to counsels are they, And there is no understanding in them.
