What is "kodashim"

Kodashim or Kod'shim or Qodhashim ( "Holy Things") is the fifth Order in the Mishnah (also the Tosefta and Talmud). Of the six Orders of the Mishnah, it is the third longest. Kodoshim deals largely with the religious service within the Temple in Jerusalem, the qorbanot ("sacrificial offerings"), and other subjects considered or related to these "Holy Things".
