ייִדישער מחשבֿה אויף מלאכי 3:19

In this way, my brother, we are obligated to be prepared for the appointed time, and to prepare for the faraway journey to the other world, which we have no escape from, and no refuge from, and to think on the provisions, and with what we will greet our Creator on the great day of accounting which scriptures says of it: "For, behold, the day is coming, it burns as a furnace; and all the proud, and all that work wickedness, shall be stubble; and the day that comes shall set them ablaze, says the L-ord of Hosts, that it shall leave them neither root nor branch" (Malachi 3:19).

(4) When one contemplates on the service he owes to G-d for the benevolent goodness and abundant kindness bestowed on him, and he considers how much he has neglected the precepts and fallen short in their observance, both those which reason mandates and those which the torah commands, and how his pleas and excuses will be cut short when the day of reckoning comes and he will be full of regret on the great day of assembly. Then he will be submitted and his spirit will be broken, as written "For lo, the day comes, glowing like a furnace, and all the audacious sinners and all the perpetrators of wickedness will be stubble. And the sun that comes shall burn them up so that it will leave them neither root nor branch, says the L-ord of Hosts" (Malachi 3:19), and "who can endure the day He comes" (Malachi 3:2).

Regarding the pleasure (in the afterlife), it is written: "And when you see this, your heart shall rejoice" (Yeshaya 66:14), and "the sun of mercy shall rise with healing in its wings for you who fear My Name. Then will you go forth and be rich as fatted calves" (Malachi 3:20), while regarding the pain it is written: "And they shall go forth, and look upon the carcasses of the men that have transgressed against Me: for their worm shall not die, neither shall their fire ever be quenched; [and they shall be an eternal abhorrence unto all flesh]" (Yeshaya 66:24), and "For lo, the day comes, that shall burn like a furnace, and all the audacious sinners and all the perpetrators of wickedness shall be stubble. And the sun that comes shall burn them up so that it will leave them neither root nor branch, says the L-ord of Hosts" (Malachi 3:19). When the sinner puts this matter to heart, he will deem it proper to take on himself not to repeat his sin.
