'Study' in the Bible

And further, by these, my son, be admonished: of making many books there is no end; and much study is a weariness of the flesh.

And that ye study to be quiet, and to do your own business, and to work with your own hands, as we commanded you;

Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
