Deuteronomy 10:4

And he wrote on the tables according to the first writing,.... The same laws, in the same letters:

the ten commandments which the Lord spake unto you in the mount; in Mount Sinai, on which he descended, and from whence he delivered the decalogue by word of mouth in an audible manner, that all the people could hear it:

out of the midst of the fire; in which he descended, and where he continued, and from whence he spake, so that it was indeed a fiery law;

in the day of the assembly; when all the people of Israel were assembled together at the bottom of the mount to hear it:

and the Lord gave them unto me; the two tables, when he had wrote upon them the ten commands.
