  • Genesis 4:3-8
    And in the process of time it came to pass that Cain brought an offering of the fruit of the ground to the LORD. Abel also brought of the firstborn of his flock and of their fat. And the LORD respected Abel and his offering, but He did not respect Cain and his offering. And Cain was very angry, and his countenance fell. So the LORD said to Cain, "Why are you angry? And why has your countenance fallen? If you do well, will you not be accepted? And if you do not do well, sin lies at the door. And its desire is for you, but you should rule over it." Now Cain talked with Abel his brother; and it came to pass, when they were in the field, that Cain rose up against Abel his brother and killed him.

  • Ezekiel 21:8-11
    Again the word of the LORD came to me, saying, “Son of man, prophesy and say, ‘Thus says the LORD!’ Say:
    ‘ A sword, a sword is sharpened
    And also polished!
    Sharpened to make a dreadful slaughter,
    Polished to flash like lightning!
    Should we then make mirth?
    It despises the scepter of My son,
    As it does all wood.
    And He has given it to be polished,
    That it may be handled;
    This sword is sharpened, and it is polished
    To be given into the hand of the slayer.’

     
  • Habakkuk 1:8

    Their cavalry comes from afar;
    They fly as the eagle that hastens to eat.
