Leviticus 24:13 - Ellicott's Commentary On The Whole Bible

And the Lord spake unto Moses. — In none of these instances, however, is it stated how and where Moses made this appeal to God, whether he inquired by means of the Urim and Thummim, or otherwise. As God promised to reveal His will to Moses from the mercy-seat between the cherubim (Exodus 25:22), it is probable that the lawgiver received the Divine directions in the sanctuary.
