Those who were willing and had the ability to do the work joyfully committed themselves to making the Tabernacle a work of art. “Those who were willing…” appears several times. For what it’s worth, the New Living Translation is much easier to read through this section. They convert cubits to feet and weights to pounds. It may seem trivial, but 150-foot wall means more than a wall of 100 cubits. I have a small brain.
36 Now whenever the cloud lifted from the Tabernacle, the people of Israel would set out on their journey, following it. 37 But if the cloud did not rise, they remained where they were until it lifted. 38 The cloud of the Lord hovered over the Tabernacle during the day, and at night fire glowed inside the cloud so the whole family of Israel could see it. This continued throughout all their journeys. Exodus 40:36-38
The closing words of Exodus conclude the tribute to those who willingly worked to build the Tabernacle, Moses’ blessing on them and the Lord’s response was to be with them in the cloud.
