As it has been supposed by some that the book of Psalms merely consists of hymns to God and sacred songs and that we shall look in vain in it for predictions and prophecies of the future, let us realize distinctly that it contains many prophecies, far too many to be quoted now, and it must suffice for proof of what Isaiah to make use of two psalms ascribed to Asaph, written in the time of David. For Asaph was one of the temple musicians then, as is stated in the book of Chronicles, and was inspired by the divine Spirit to speak the psalms inscribed with his name―Eusebius of Caesarea

Although fire seems to human intelligence to be incapable of being cut or divided, yet by the command of the Lord it is cut through and divided. I believe that the fire prepared in punishment for the devil and his angels is divided by the voice of the Lord, in order that, since there are two capacities in fire, the burning and the illuminating, the fierce and punitive part of the fire may wait for those who deserve to burn, while its illuminating and radiant part may be allotted for the enjoyment of those who are rejoicing. Therefore, the voice of the Lord divides the fire and allots it, so that the fire of punishment is dark, but the light of the state of rest remains unkindled—St Basil the Great

After that [the killing of Goliath] he never entered on a war without seeking counsel of the Lord. Thus he was victorious in all wars, and even to his last years [he] was ready to fight. And when war arose with the Philistines, he joined battle with their fierce troops, being desirous of winning renown, while careless of his own safety (2 Sam 21:15). But this is not the only kind of fortitude which is worthy of note. We consider their fortitude glorious, who, with greatness of mind, "through faith stopped the mouth of lions, quenched the violence of fire, escaped the edge of the sword, out of weakness were made strong," (Heb 11:33–34) They did not gain a victory in common with many, surrounded by comrades and aided by the legions, but [they] won their triumph alone over their treacherous foes by the mere courage of their own souls―St Ambrose of Milan
