Albert Barnes Commentary Ezekiel 40:42

"And there were four tables for the burnt-offering, of hewn stone, a cubit and a half long, and a cubit and a half broad, and one cubit high; whereupon they laid the instruments wherewith they slew the burnt-offering and the sacrifice." — Ezekiel 40:42 (ASV)

Omit “the” and “were.” These “four tables” are not the same as those mentioned before. The eight tables (T) were for slaying and preparing the victims and were probably of wood; these (S) were of “hewn stone.” There may be in the number twelve a reference to the twelve tribes of Israel.
