Contradiction with Leviticus 11:4
This verse contradicts Genesis 18:8 by forbidding the consumption of certain animals, while Abraham served potentially non-kosher food.
Leviticus 11:4: Nevertheless these shall ye not eat of them that chew the cud, or of them that divide the hoof: [as] the camel, because he cheweth the cud, but divideth not the hoof; he [is] unclean unto you.
Contradiction with Genesis 9:4
This verse contradicts Genesis 18:8 by prohibiting the consumption of blood, which could have occurred during meal preparation without strict adherence.
Genesis 9:4: But flesh with the life thereof, [which is] the blood thereof, shall ye not eat.
Paradox #1
The possible contradiction in Genesis 18:8 involves the timing and dietary customs. The verse mentions offering a meal with meat and dairy together, which could conflict with later Jewish dietary laws prohibiting mixing meat and dairy. However, these laws were formalized after the events of Genesis, which means this inconsistency could be seen as an anachronism or as indicating different practices before the laws were established.
