'Arise' in the Bible

And the asses of Kish Saul's father were lost. And Kish said to Saul his son, Take now one of the servants with thee, and arise, go seek the asses.

And he sent, and brought him in. Now he was ruddy, and withal of a beautiful countenance, and goodly to look to. And the LORD said, Arise, anoint him: for this is he.

Then David inquired of the LORD yet again. And the LORD answered him and said, Arise, go down to Keilah; for I will deliver the Philistines into thine hand.
