'Post' in the Bible

Then the king stood at his post and made a covenant in the Lord’s presence to follow the Lord and to keep His commands, His decrees, and His statutes with all his heart and with all his soul in order to carry out the words of the covenant written in this book.

For the Lord has said to me,“Go, post a lookout;let him report what he sees.

Then the lookout reported,“Lord, I stand on the watchtower all day,and I stay at my post all night.

Raise up a signal flagagainst the walls of Babylon;fortify the watch post;set the watchmen in place;prepare the ambush.For the Lord has both planned and accomplishedwhat He has threatenedagainst those who live in Babylon.

I will stand at my guard postand station myself on the lookout tower.I will watch to see what He will say to meand what I should reply about my complaint.
