Her princes were purer than snow, they were whiter than milk, they were more ruddy in body than rubies, their appearance was of sapphire:
All Commentaries on Lamentations 4:7 Go To Lamentations 4
Gregory the Theologian
AD 390
Take my advice, my friend, and be slow to do evil but swift to your salvation; for readiness to evil and tardiness to good are equally bad. If you are invited to a revel, be not swift to go; if to apostasy, leap away; if a company of evildoers say to you, “Come with us, share our blood guiltiness, let us hide in the earth a righteous person unjustly,” do not lend them even your ears. Thus you will make two very great gains; you will make known to the other his sin, and you will deliver yourself from evil company. But if David the Great says to you, Come and let us rejoice in the Lord, or another prophet, Come and let us ascend into the mountain of the Lord, or our Savior himself, Come to me, all you who labor and are heavy laden, and I will give you rest, or, Arise, let us go hence, shining brightly, glittering above snow, whiter than milk, shining above the sapphire stone, let us not resist or delay. Let us be like Peter and John, and let us hasten, as they did to the sepulcher and the resurrection, so we to the font; running together, racing against each other, striving to be first to obtain this blessing.
