Found in Testament or a Hebrew sacred scroll (5)
I believe the answer is:
torah
'sacred scroll' is the definition.
The definition suggests a singular noun which matches the answer.
'found in testament or a hebrew' is the wordplay.
'found in' indicates a hidden word.
'TORAH' is hidden within 'testament or a hebrew'.
Can you help me to learn more?
(Other definitions for torah that I've seen before include "The law of God as revealed to Moses" , "Jewish scripture" , "Jewish law" , "Pentateuch" , "Law as revealed to Moses (Judaism)" .)
