'Down' in the Bible

For all his days are sorrows, and his travail sadness; even at night his heart hath not lain down; this also is vanity.

A time to slay, And a time to heal, A time to break down, And a time to build up.

Who knoweth the spirit of the sons of man that is going up on high, and the spirit of the beast that is going down below to the earth?

Also, if two lie down, then they have heat, but how hath one heat?

And doors have been shut in the street. When the noise of the grinding is low, And one riseth at the voice of the bird, And all daughters of song are bowed down.
