'Behind' in the Bible

Now Elisha was sitting in his house, and the elders were sitting with him. And the king sent a man ahead of him [to behead Elisha]; but before the messenger arrived, Elisha told the elders, “Do you see how this son of [Jezebel] a murderer has sent [a man] to remove my head? Look, when the messenger comes, shut the door and hold it securely against him. Is not the sound of his master’s feet [just] behind him?”

So the horseman went to meet him and said, “Thus says the king: ‘Do you come in peace?’” And Jehu said, “What have you to do with peace? Rein in behind me.” And the watchman reported, “The messenger approached them, but he has not returned.”

Then Joram sent out a second horseman, who approached them and said, “Thus says the king: ‘Do you come in peace?’” Jehu replied, “What have you to do with peace? Rein in behind me.”

(a third shall also be at the [city] gate Sur, and a third at the gate behind the guards); so you shall keep watch over the palace [from three posts] for defense.

This is the word that the Lord has spoken against him:‘The virgin daughter of ZionHas despised you and mocked you;The daughter of JerusalemHas shaken her head behind you!
