'Self control' in the Bible

Do not defraud one another, except perhaps by agreement, for a time, in order that you may devote yourselves to prayer, and [then] you should be {together} again, lest Satan tempt you because of your lack of self control.

And everyone who competes exercises self-control in all [things]. Thus those [do so] in order that they may receive a perishable crown, but we an imperishable [one].
