Deuteronomy 9:10

And the Lord delivered unto me two tables of stone, written
with the finger of God
The letters were of his devising and forming, the writing was his, the engraving them on the stones was his own doing; and which was done to show its original, to stamp a divine authority on it, and to denote its duration; see ( Exodus 31:18 ) ( 32:16 )

and on them was written according to all the words which the Lord spake
with you in the mount;
the ten commands, exactly in the same order, and in the same words, without any variation, as they were delivered to them with an articulate voice in their hearing; but now were written in this manner, that they might be read by them, and remain with them, see ( Exodus 34:28 )

out the midst of the fire;
in which the Lord was, and whence he spake:

in the day of the assembly;
when all the people of Israel were gathered together at the foot of the mount; see ( Exodus 19:17 ) ( Deuteronomy 4:10-12 ) .
