Deuteronomy 10:3

So I made an ark of boards of incorruptible wood, and I hewed tables of stone like the first, and I went up to the mountain, and the two tables were in my hand.

And I made an ark of shittim wood, and hewed two tables of stone like unto the first, and went up into the mount, having the two tables in mine hand.

So I made an ark of acacia wood, and cut two stone tablets like the first, and went up onto the mountain, having the two tablets in my hand.
