'Post' in the Bible

Meanwhile, Absalom had run away. While the young man standing watch was looking around, all of a sudden he observed many people coming down the road behind and to the west of the mountain! So the watchman left his post and reported, "I have seen men coming from the direction of Horonaim."

For this is what the LORD told me: "Go post a lookout. Have him report what he sees.

Then the lookout shouted: "Upon a watchtower I stand, O Lord, continually by day, and I am stationed at my post throughout the night.

Lift up the battle standard against Babylon's walls. Strengthen the guard; post watchmen. Set men in position for an ambush. For the LORD will both plan and carry out what he has declared against the inhabitants of Babylon.

"I will stand at my guard post and station myself on a tower. I will wait and see what the LORD will say about me and what I will answer when he reprimands me."
