Shemot 26:22-24

Orthodox Jewish Bible

²² And for the back of the Mishkan on the west, thou shalt make six kerashim (planks).

²³ And two kerashim (planks) shalt thou make for the corners of the Mishkan in the rear.

²⁴ And they shall be even beneath at the bottom, and they shall be joined together at the top of it unto one ring: thus shall it be for them both; they shall be for the two corners.
