'Untrained' in the Bible

An untrained ass, used to the waste land, breathing up the wind in her desire; at her time, who is able to send her away? all those who are looking for her will have no need to make themselves tired; in her month they will get her.

I have heard Ephraim moaning,“You disciplined me, and I have been disciplinedlike an untrained calf.Restore me, and I will return,for you, Lord, are my God.
