Deuteronomy 10:1-3

1“At that time the Lord said to me, ‘Cut out for yourself two tablets of stone like the first, and come up to Me on the mountain, and make an ark (chest) of wood for yourself.

2I will write on the tablets the words that were on the first tablets which you shattered, and you shall put them in the ark.’

3So I made an ark of acacia wood and cut out two tablets of stone like the first, and went up the mountain with the two tablets in my hand.
