Here's an article on R. Crumb's version of Genesis which was released last month. He's an old time underground comic artist for those of you who are unfamiliar with the name.

The New York Times has an article with excerpts, but you need to be registered to see it I think. I am and it's free. Google will get you to it pretty easily.
Basil Wolverton started a little earlier than Crumb and was also a pretty well known comic artist. He was also a Christian and illustrated the Old Testament and the Book of Revelations.

His Revelations pics are pretty easy to find via Google too.
I'd sure like to see Charles Burns take the subject on.
In a more traditional vein, Judith with the head of Holofernes was a pretty popular Renaissance subject. Caravaggio and Artemisia Gentileschi painted her in the act of removing it. The place they really went crazy back then was in their depictions of the ecstatic suffering of martyrs or of people being "questioned" by the church during the inquisition. The Spanish especially the Catalans were probably the most extreme with that. If you can speak, or actually if you can write in Spanish, French, or Italian, you could easily find a lot of that through Google image searches or book searches. There's a lot more available if you can access academic journals through a university link.
Theodore Gericault isn't known for Biblical themes, but for years he did make preliminary studies for his Raft of the Medusa for which he kept various human heads and other parts around his studio. He was a really extraordinary artist and insisted on accuracy in his figures. Of course Michelangelo and Leonardo did the same.
Claudicci, since you do know German, you might look into Ernst Fuch's work. His imagery is rarely gruesome, but it is a very mystical take on those themes. He has also done a Judith if I recall correctly.
