'Heads' in the Bible

Now a river flowed out of Eden to water the garden; and from there it divided and became four [branching] rivers.

Now on the third day, [which was] the Pharaoh’s birthday, he [released the two men from prison and] made a feast for all his servants; and he lifted up the head of the chief cupbearer and the head of the chief baker [that is, presented them in public] among his servants.

And they answered, “Your servant our father is in good health; he is still alive.” And they bowed down [their heads before Joseph] in respect.
