'Inside' in the Bible

You shall overlay the ark with pure gold, overlay it inside and out, and you shall make a gold border (frame) around its top.

You shall put into the ark the Testimony (Ten Commandments) which I will give you.

You shall make two gold rings and put them at the two ends of the breastpiece, on its inside edge next to the ephod.

They made two rings of gold and put them on the two ends of the breastpiece, on its inner edge which was next to the ephod.
