The Haftarah is a text selected from the books of Nevi’im [Prophets] that is read publicly in the synagogue after the reading of the Torah on each Sabbath, as well as on the “Feasts of the L-rd” [festivals], and fast days. The most common explanation, accepted by some traditional Jewish authorities is that in 168 B.C.E., when the Jews were under the rule of the Seleucid king Antiochus IV Epiphanes, Chanukah Story [This is the Feast of Dedication/Chanukah of John 10:22, that Yeshua attended], they were forbidden from reading the Torah and made do by substituting a section of the rest of the Tanakh (The Prophets- Nevi’im). When they were again able to read the Torah (Five books of Moses), they kept reading the haftarah (the corresponding Prophet reading) as well.

BERESHIT / Gen 4:1 The man had sexual relations with Havah his wife; she conceived, gave birth to Kayin [acquisition] and said, “I have acquired a man from Adonai.” 2 In addition she gave birth to his brother Hevel. Hevel kept sheep, while Kayin worked the soil. 3 In the course of time Kayin brought an offering to Adonai from the produce of the soil; 4 and Hevel too brought from the firstborn of his sheep, including their fat. Adonai accepted Hevel and his offering 5 but did not accept Kayin and his offering. Kayin was very angry, and his face fell. 6 Adonai said to Kayin, “Why are you angry? Why so downcast? 7 If you are doing what is good, shouldn’t you hold your head high? And if you don’t do what is good, sin is crouching at the door — it wants you, but you can rule over it.” 8 Kayin had words with Hevel his brother; then one time, when they were in the field, Kayin turned on Hevel his brother and killed him.
