'Heads' in the Bible

Thus they lifted up their eyes from afar, but they did not recognize him, so they raised their voice, and they wept, and each man tore his outer garment and threw dust on their heads {toward the sky}.

He strips [away] the insight of the heads of the earth's people, and he makes them wander in {a pathless wasteland}.

They are exalted a little while, then {they are gone}. And they are brought low; they are cut off like all [others], and like [the] heads of grain they wither away.
