'Behind' in the Bible

I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet,

And before the throne there was a sea of glass like unto crystal: and in the midst of the throne, and round about the throne, were four beasts full of eyes before and behind.

So I looked and here came a pale green horse! The name of the one who rode it was Death, and Hades followed right behind. They were given authority over a fourth of the earth, to kill its population with the sword, famine, and disease, and by the wild animals of the earth.

From its mouth the serpent spewed water like a river behind the woman in order to sweep her away with the flood.
