According to the Hebrew Bible, the Tablets of the Law (also Tablets of Stone, Stone Tablets, or Tablets of Testimony; Biblical Hebrew: לוּחֹת הַבְּרִית lûḥōt habbǝrît "tablets of the covenant", לֻחֹת הָאֶבֶן lūḥōt hāʾeben or לֻחֹת אֶבֶן lūḥōt eben or לֻחֹת אֲבָנִים lūḥōt ʾăbānîm "stone tablets", and לֻחֹת הָעֵדֻת lūḥōt hāʿēdūt "tablets of testimony", Arabic: أَلْوَاحُ مُوسَى) were the two stone tablets inscribed with the Ten Commandments when Moses ascended Mount Sinai as written in the Book of Exodus.
