'Behind' in the Bible

But Elisha sat in his house, and the elders sat with him; and the king sent a man from before him: but ere the messenger came to him, he said to the elders, See ye how this son of a murderer hath sent to take away mine head? look, when the messenger cometh, shut the door, and hold him fast at the door: is not the sound of his master's feet behind him?

So there went one on horseback to meet him, and said, Thus saith the king, Is it peace? And Jehu said, What hast thou to do with peace? turn thee behind me. And the watchman told, saying, The messenger came to them, but he cometh not again.

Then he sent out a second on horseback, which came to them, and said, Thus saith the king, Is it peace? And Jehu answered, What hast thou to do with peace? turn thee behind me.

And a third part shall be at the gate of Sur; and a third part at the gate behind the guard: so shall ye keep the watch of the house, that it be not broken down.
