“And they who gave in their branches half-green and half-withered, are those who are immersed in business, and do not cleave to the saints. For this reason, the one half of them is living, and the other half dead. Many, accordingly, who heard my commands repented, and those at least who repented had their dwelling in the tower. But some of them at last fell away: these, accordingly, have not repentance, for on account of their business they blasphemed the Lord, and denied Him.
They therefore lost their lives through the wickedness which they committed. And many of them doubted. These still have repentance in their power, if they repent speedily; and their abode will be in the tower. But if they are slower in repenting, they will dwell within the walls; and if they do not repent, they too have lost their lives. And they who gave in their branches two-thirds withered and one-third green, are those who have denied [the Lord] in various ways. Many, however, repented, but some of them hesitated and were in doubt. These, then, have repentance within their reach, if they repent quickly, and do not remain in their pleasures; but if they abide in their deeds, these, too, work to themselves death.”
