Halakhah su Proverbi 20:27

Therefore G-d found it necessary to create man on the sixth day, and He created him with competing drives: Man possesses a spiritual soul that enables him to recognize the creator as does an angel, as the verse states: “Man’s soul is G-d’s lamp…” (Mishlei 20:27). He also possesses an animalistic nature due to his physical body, which drives him to animal behaviors, such as eating, drinking, and sleeping.This state of affairs gives rise to a constant struggle within man all the days of his life, with his animal nature pining for physical desires, while his pure soul opposes such pursuits, inspiring man to turn to his real purpose, to serve G-d like an angel. His soul further insists that even necessary physical needs, such as eating, drinking, and sleeping, should be done with intent to better serve G-d, and on this the verse has been stated: “I have placed G-d before me constantly.” (Psalms 16:8). After man’s death he is shown on high that all his actions were recorded, as though in a book, with his own signature. If he has followed the path of Torah and mitzvos, he inherits heaven (Lit. 'Gan Eden') which is a limitless and endless spiritual joy. Of these people the verse proclaims "They will be sated from the fat of Your house, and with the stream of Your delights You give them to drink. For with You is the source of life; in Your light we will see light. " (Psalms 36:9). If G-d forbid his actions were the opposite, he inherits Gehenom, to which all the pains of this life are as naught in comparison. On these people the verse states: "And they shall go out and see the corpses of the people who rebelled against Me, for their worm shall not die, and their fire shall not be quenched, and they shall be an abhorring for all flesh." (Yishayahu 66:24). There are seven descriptions given to Gehenom: Nether-world (or Sheol), Destruction, Pit, Tumultuous Pit, Miry Clay, Shadow of Death and the Underworld. (Eruvin 19a). One who is seduced by his base inclinations falls there, and that is why it is also called 'seducer', as the verse states "For Tophteh (Heb. related to the word 'seduce') is set up from yesterday, that too has been prepared for the king (Sennacherib and his army), it deepened, it widened its pile, of fire and much wood; the breath of the Lord is like a stream of brimstone, burning therein.(Yishayahu 30:33). (Eruvin 19a).

7. The Rambam in the laws of Tzizith Chapter II Halacha II gives in the sign to recognize the Hillazon and this is his holy words. Its a fish whose color resembles that of Techelet and whose blood is black as ink. I have found no source in the Talmud in support of Rambam words that its blood is black as ink. And it appears from this that after Rambam wrote his commentary on the Mishnah he toiled and labored until he found the Hillazon according to the signs mentioned in the words of our Sages of Blessed Memory and fulfilled the Precept Mitzvah of Techelet. Then he proceeded to enumerate other signs that could be found in it such as its black ink like blood. He though that perhaps it would be forgotten this would make it easier for one who desired to search for it and be able to find it without giving up. For if Rambam did not make it known to us (regarding its black blood) we would search for it relying solely on the signs in the Talmud. And even if we would find it we would lose hope saying that since its blood is black this is certainly not the Hillazon needed to dye the Techelet, Therefore he made it known to us that in truth its blood is black and only by adding of the substances is it possible to dye it the color of Techelet.
