Exodus 36:22-24

Revised Standard Version

²² Each frame had two tenons, for fitting together; he did this for all the frames of the tabernacle. ²³ The frames for the tabernacle he made thus: twenty frames for the south side; ²⁴ and he made forty bases of silver under the twenty frames, two bases under one frame for its two tenons, and two bases under another frame for its two tenons.
