'Trained' in the Bible

One friend deceives another and no one tells the truth. These people have trained themselves to tell lies. They do wrong and are unable to repent.

And I am as a trained lamb brought to slaughter, And I have not known That against me they have devised devices: We destroy the tree with its food, and cut him off From the land of the living, And his name is not remembered again.

What will you say when He appointsclose friends as leaders over you,ones you yourself trained?Won’t labor pains seize you,as they do a woman in labor?

Can an Ethiopian change his skin, or a leopard his spots? Then you who are trained to do evil will also be able to do good.

I have indeed heard Ephraim bemoaning himself thus: Thou hast chastised me, and I was chastised as a bullock not trained: turn thou me, and I shall be turned; for thou art Jehovah my God.
