Numbers 4:31

4:31 This is what they are responsible to carry as their entire service in the tent of meeting: the frames ¹  of the tabernacle, its crossbars, its posts, its sockets,

Numbers 12:5

12:5 And the Lord came down in a pillar of cloud and stood at the entrance of the tent; he then called Aaron and Miriam, and they both came forward.

[4:31]  ¹ sn More recent studies have concluded that these “boards” were made of two long uprights joined by cross-bars (like a ladder). They were frames rather than boards, meaning that the structure under the tent was not a solid building. It also meant that the “boards” would have been lighter to carry.
