'Self restraint' in the Bible

Every athlete exercises self-restraint in everything; they, indeed, for a crown that fades, we for one that is unfading.

On the contrary, he should be hospitable, eager for the right discreet, upright, a man of holy life and capable of self-restraint,

But the end of all things is near. Therefore exercise self-restraint and be calm, that you may be able to pray.
