TSK · Luke 11:51

The Spirit of God came on Zechariah the son of Jehoiada the priest; and he stood above the people, and said to them, "Thus says God, 'Why do you disobey the commandments of Yahweh, so that you can't prosper? Because you have forsaken Yahweh, he has also forsaken you.'"

In the eighth month, in the second year of Darius, the word of Yahweh came to Zechariah the son of Berechiah, the son of Iddo, the prophet, saying,

By faith, Abel offered to God a more excellent sacrifice than Cain, through which he had testimony given to him that he was righteous, God testifying with respect to his gifts; and through it he, being dead, still speaks.

unlike Cain, who was of the evil one, and killed his brother. Why did he kill him? Because his works were evil, and his brother's righteous.
