“But refuse profane and old wives' fables, and exercise thyself rather unto godliness.”
King James Version (KJV)
4:7 Like those who were to contend in the Grecian games, exercise thyself unto godliness - Train thyself up in holiness of heart and life, with the utmost labour, vigour, and diligence.
1Ti 4:7 Refuse profane and old wives' fables. The foolish myths and legends of the heathen, and also the marvelous additions which Jewish rabbis had made to the Old Testament. Reject all these. Exercise thyself [rather] unto godliness. Train thyself to a godly life, as a gymnast trains himself to bodily exercise.
