Exodus 27:8

8Make the altar hollow, out of boards. It is to be made just as you were shown on the mountain.

8You shall make it hollow with planks; as it was shown to you on the mountain, so they shall make it.

8You shall make it hollow with planks; as it was shown to you in the mountain, so they shall make it.

8You are to make the altar hollow with planks; as you were shown on the mountain [of Sinai], so shall it be made.

8Construct the altar with boards so that it is hollow. It is to be made just as you were shown on the mountain.

8Make the altar out of boards. Leave it hollow. It must look just like what I showed you on the mountain.
