Unity

There’s not I remember from my college physics class. I remember why gravity works, why popcorn pops, and that British professors are cute. And there was something about the power of water as it travels through pipes. I don’t remember the formula, but it had to do with the circumference of the pipe and the velocity of the water, and probably force or something too. But this part I remembered clearly. No matter how powerful the water was at the beginning, if you split the pipe into 2, the power was lessened. And the more times the pipe split, the weaker it became. (But don’t worry, the professor’s cuteness was always a constant factor, no matter how weak the force was.)
God told the Isrealites to create a tabernacle where he could come and dwell among his people. And he gave them very specific instructions.
Most times, I just kinda skim through them . They always seem tedious and boring. However this time I actually paid attention.
Do you know what I saw there? Repetition, and a focus on unity.
For example, the instructions for making a lampstand:

Make a lampstand of pure, hammered gold. The entire lampstand and its decorations will be one piece – the base, center stem, lamp cups, buds, and blossoms. 32 It will have six branches, three branches going out from each side of the center stem. 33 Each of the six branches will hold a cup shaped like an almond blossom, complete with buds and petals. 34 The center stem of the lampstand will be decorated with four almond blossoms, complete with buds and petals. 35 One blossom will be set beneath each pair of branches where they extend from the center stem. 36 The decorations and branches must all be one piece with the stem, and they must be hammered from pure gold. 37 Then make the seven lamps for the lampstand, and set them so they reflect their light forward. 38 The lamp snuffers and trays must also be made of pure gold. 39 You will need seventy-five pounds F48 of pure gold for the lampstand and its accessories. 40 "Be sure that you make everything according to the pattern I have shown you here on the mountain.
Every part is to be one piece, and set to reflect their light forward. And he adds at the end “Be sure to make everything according to the pattern I have shown you here on the mountain.” (emphasis mine) and goes on to give more instructions for the tabernacle, often using the phrases, “forming a single unit” “making it a single unit,” and “made of one piece”
Now I’m no trying to create a whole new doctrine of these chapters, but I think it’s interesting that God requests unit from his people, even in the seemingly mundane details.
Why?
There’s strength and power in unity.
