but Jesus having called them near, saith to them, 'Ye have known that they who are considered to rule the nations do exercise lordship over them, and their great ones do exercise authority upon them;

And he said to them, 'The kings of the nations do exercise lordship over them, and those exercising authority upon them are called benefactors;

and in this I do exercise myself, to have a conscience void of offence toward God and men always.

and the profane and old women's fables reject thou, and exercise thyself unto piety,

for the bodily exercise is unto little profit, and the piety is to all things profitable, a promise having of the life that now is, and of that which is coming;
