Moses
Exodus 38:18ESV·traditional attribution

And the screen for the gate of the court was embroidered with needlework in blue and purple and scarlet yarns and fine twined linen. It was twenty cubits long and five cubits high in its breadth, corresponding to the hangings of the court.

Matthew Henry Presbyterian @wholebiblehenry

The walls of the court, or church-yard, were like the rest curtains or hangings, made according to the appointment, Exo 27:9, etc. This represented the state of the Old Testament church: it was a garden enclosed; the worshippers were then confined to a little compass. But the enclosure being of curtains only intimated that the confinement of the church in one particular nation was not to be perpetual.

the height in the breadth--or, "in the measure." The sense is that the hangings of the court gate, which was twenty cubits wide, were of the same height as the hangings all round the court [WALL].
