Paul warned the Hebrews: “Beware, brothers, for fear there should ever develop in any one of you a wicked heart lacking faith by drawing away from the living God; but keep on exhorting one another each day, as long as it may be called ‘ Today, ’ for fear any one of you should become hardened by the deceptive power of sin. ”
עודדו איש את רעהו יום יום, כל עוד הזמן מכונה ’ היום ’, למען לא יקשה לב איש מכם בנכלי החטא ” (‏ עברים ג ’: 12, 13‏).
