genesis 12-19

Genesis 13-16 And I will make thy seed as the dust of the earth: so that if a man can number the dust of the earth, then shall thy seed also be numbered. This is saying that I will make your descendants number the as large as the dust of the earth. Genesis 15-17 and it came to pass that, when the sun went down, and it was dark, behold a smoking furnace, and a burning lamp that passed between those peaces. In this the Lord is depicted as a smoking furnace and a torch, which seems weird. Genesis 18-25 he is saying to God how can you treat the inocent and the gilty the same.
