'Bonnets' in the Bible

And your bonnets are on your heads, And your shoes are on your feet, Ye do not mourn nor do ye weep, And ye have wasted away for your iniquities, And ye have howled one unto another.

They shall have linen bonnets upon their heads, and shall have linen breeches upon their loins; they shall not gird themselves with any thing that causeth sweat.
