In this chapter, the word of the Lord comes to Abram in a vision, but then also brings him outside because words can move around like people in visions. God re-promises the whole countless descendants things which Abram allegedly believes, which is seen as righteousness (somehow being convinced of something is righteous), but then immediately questions the thing the narrator said he believed. So Abram does a brutal ritual which, if done today, would be illegal and probable presumed satanic. Not surprisingly, Abram feels pretty heavy after cutting up 3 animals so he goes to sleep and misses the display of smoking pottery and fire.
