As a child, I have always been fascinated with biblical stories, especially by the way Hashem intervened powerfully and personnally in people's lives.
I was in awe in front of the story of the writing on the wall, taken out of the book of Daniel. God would write prophetic words with His own hand and the king would be able to see it!
