Sirach 2:4

Ben Sira, Ecclesiasticus

2 Set your heart right and be steadfast, and do not be impetuous in time of calamity. 3 Cling to him and do not depart, so that your last days may be prosperous. 4 Accept whatever befalls you, and in times of humiliation be patient. 5 For gold is tested in the fire, and those found acceptable, in the furnace of humiliation. 6 Trust in him, and he will help you; make your ways straight, and hope in him.

Cyprian Treatises 9:17

17 And moreover, also, for the varied ills of the flesh, and the frequent and severe torments of the body, wherewith the human race is daily wearied and harassed, patience is necessary. For since in that first transgression of the commandment strength of body departed with immortality, and weakness came on with death-and strength cannot be received unless when immortality also has been received — it behooves us, in this bodily frailty and weakness, always to struggle and to fight. And this struggle and encounter cannot be sustained but by the strength of patience. But as we are to be examined and searched out, diverse sufferings are introduced; and a manifold kind of temptations is inflicted by the losses of property, by the heats of fevers, by the torments of wounds, by the loss of those dear to us. Nor does anything distinguish between the unrighteous and the righteous more, than that in affliction the unrighteous man impatiently complains and blasphemes, while the righteous is proved by his patience, as it is written: In pain endure, and in your low estate have patience; for gold and silver are tried in the fire.
