'Heads' in the Bible

The Lord says, "The women of Zion are proud. They walk with their heads high and flirt with their eyes. They skip along and the jewelry on their ankles jingles.

So the sovereign master will afflict the foreheads of Zion's women with skin diseases, the Lord will make the front of their heads bald."

At that time the sovereign master, the Lord who commands armies, called for weeping and mourning, for shaved heads and sackcloth.

For the Lord has poured out on you a strong urge to sleep deeply. He has shut your eyes (the prophets), and covered your heads (the seers).

Is this really the kind of fasting I want? Do I want a day when people merely humble themselves, bowing their heads like a reed and stretching out on sackcloth and ashes? Is this really what you call a fast, a day that is pleasing to the Lord?
