Rashi on Exodus 26:36/רש"י על שמות כ״ו:ל״ו

1ועשית מסך AND THOU SHALT MAKE A SCREEN — a curtain which formed a protecting screen in front of the entrance. the word מסך being of the same meaning as the verb in (Job 1. 10) “Hast Thou not hedged (שכת) him about?” It is an expression denoting protecting.

2מעשה רקם THE WORK OF AN EMBROIDERER — The designs were made on it by needle-work; as were the figures on one side so were the figures on the other side.

3רקם — This word is the name of the workman (an embroiderer), not the name of the trade (embroidery). The Targum therefore should be עובד צַיָּר “work of an embroiderer,” not עובד צִיּוּר “work of embroidery.” The size of the screen was the same as the size of the partition veil, viz., 10 cubits by 10 cubits.
