'Training' in the Bible

And the king assigned to them {his daily portion} from the fine food of the king, and from {the wine that he drank}, and [instructed that] {they were to be educated for three years}. And at the end [of] their [training], {they were to be stationed} {before} the king.

For the training of the body is {somewhat} profitable, but godliness is profitable for everything, [because it] holds promise for the present life and for the [life] to come.

All scripture [is] inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness,

training us in order that, denying impiety and worldly desires, we may live self-controlled and righteously and godly in the present age,
