John Gill Commentary Deuteronomy 10:4

"And he wrote on the tables, according to the first writing, the ten commandments, which Jehovah spake unto you in the mount out of the midst of the fire in the day of the assembly: and Jehovah gave them unto me." — Deuteronomy 10:4 (ASV)

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

the ten commandments which the Lord spoke to you in the mount ; in Mount Sinai, on which he descended, and from which 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 which he spoke, 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 to me ; the two tables, when he had wrote upon them the ten commands.
