In Exodus 25:10 (NASB)
“They shall construct an ark of acacia wood two and a half cubits long, and one and a half cubits wide, and one and a half cubits high. 11 You shall overlay it with pure gold, inside and out you shall overlay it, and you shall make a gold molding around it.
Then, in Deuteronomy 10:1-2 (NASB)
1 “At that time the Lord said to me, ‘Cut out for yourself two tablets of stone like the former ones, and come up to Me on the mountain, and make an ark of wood for yourself. 2 I will write on the tablets the words that were on the former tablets which you shattered, and you shall put them in the ark.’
After having received the law Moses went up the mountain to collect the two tablets of stone at the same time receiving the instruction to build the ark. Also at the same time Aaron was making the golden calf which subsequently led to the destruction of the first set tablets.
I'm wondering... is this "ark of wood" from Deuteronomy the ark of the covenant?
