Pemikiran Yahudi Yeremia 9:4: Duties

6. That the repentance becomes too difficult for him, such as when a person became accustomed to doing it until the bad deed attached to him and became part of his nature, and it will not be easy for him to abandon it, as written: "they have taught their tongue to speak lies, and weary themselves to commit iniquity" (Yirmiya 9:4), and "Can the Ethiopian change his skin, or the leopard his spots? [then may you also do good, those that are accustomed to doing evil]" (Yirmiya 13:23).

10. One who habituated his tongue to lie and to speak of the faults of others, and to denigrate them. For he cannot remember all of what he said and all those who he spoke about due to the countless words, and forgetting the people he spoke against. It is all guarded against him and recorded in the book of his sins. On him it is said: "And if he comes to see me, he speaks vanity: his heart gathers iniquity to itself; when he goes abroad, he tells it" (Tehilim 41:7), and "When you saw a thief, you are pleased with him, and you keep company with adulterers"(Tehilim 50:18), and the rest of the matter. Behold, the verse equated evil speech with theft and adultery. So too, it is said "they deceive (corrupt) one another and do not speak the truth; they have taught their tongue to speak lies, they commit iniquity until they are weary" (Yirmiya 9:4).
