'Arise' in the Bible

The donkeys of Kish, Saul's father, were lost. Kish said to Saul his son, "Take now one of the servants with you, and arise, go seek the donkeys."

He sent, and brought him in. Now he was ruddy, and withal of a beautiful face, and goodly to look on. Yahweh said, "Arise, anoint him; for this is he."

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