Theophylact of Ohrid

Then comes self-control. For it too is needed by the one who has attained the aforementioned measure, lest he become proud of the greatness of the gift. And since with short-lived self-control one cannot secure the gift for oneself (for the passions, despite the freedom restraining them, always tend to strive toward what is worse), one must surpass it with patience. It will produce everything, and will bring godliness to peace, and will perfect hope in God.

Bede

And in temperance, patience. It is always necessary that temperance is accompanied by patience, so that whoever has learned to restrain himself from the pleasures of the world may also endure adversities with a firm heart, armed for justice from the right hand and the left (2 Corinthians 6).
