Paralipomenon \Par`a*li*pom"e*non\, n. pl. [L., fr. Gr.
   paraleipome`nwn of things omitted, pass. p. pr. (neuter
   genitive plural) fr. ? to omit.]
   A title given in the Douay Bible to the Books of Chronicles.

   Note: In the Septuagint these books are called
         Paraleipome`nwn prw^ton and dey`teron, which is
         understood, after Jerome's explanation, as meaning that
         they are supplementary to the Books of Kings --W.
