Linda Roch : Hello and welcome! If you have any other questions and please leave positive feedback.
Linda Roch : As a first source, just to understand the idea of these creatures, I would recommend Wikipedia. I would not recommend it for most things but it's a good starting point beffore you dwelve into the specifics of each of these.
Linda Roch : http://en.wikipedia.org/wiki/Behemoth
Linda Roch : http://en.wikipedia.org/wiki/Leviathan
Linda Roch : http://en.wikipedia.org/wiki/Ziz
Linda Roch : I think this is a good starting point because the religious web sites I will give you next will have a lot more biased than this site on this subject matter
Linda Roch : http://www.jewishencyclopedia.com/articles/9841-leviathan-and-behemoth
What about after Wikipedia? And where would I find depictions of what these creatures look like? Such as a picture?
Linda Roch : To find a picture, the easiest way to do it is go to Google and enter one of the creatures into the search box and press image
Linda Roch : You will get all the different depctions of the creature.
