Describing the Jewish law that fits together into a pattern (6)
I believe the answer is:
mosaic
'pattern' is the definition.
(I know that mosaic is a type of pattern)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for mosaic that I've seen before include "Design of small pieces of colored stone or glass (6)." , "It is pieced together" , "Design made of small pieces of colored stone or glass" , "Picture made up of coloured fragments" , "expressed in stones" .)
