LXX2012(i) 4 And Abel also brought of the first born of his sheep and of his fatlings, and God looked upon Abel and his gifts, 5 but Cain and his sacrifices he regarded not, and Cain was exceedingly sorrowful and his countenance fell. 6 And the Lord God said to Cain, Why are you become very sorrowful and why is your countenance fallen?
