Exodus 36:24
And forty sockets of silver he made under the twenty boards; two sockets under one board for his two tenons, and two sockets under another board for his two tenons. And forty sockets of silver he made under the twenty boards; two sockets under one board for his two tenons, and two sockets under another board for his two tenons.
The forty sockets of silver placed under the twenty boards, two sockets under one board for its two tenons and two under another board for its two tenons, belong to the account of building the tabernacle. That building required exactitude in following the given measure, together with skill, wisdom, and perfection in execution. This standard provides the pattern for every kind of work done in God's service.
