Exodus 26:9

26:9 You are to join five curtains by themselves and six curtains by themselves. You are to double over ¹  the sixth curtain at the front of the tent.

Exodus 26:12

26:12 Now the part that remains of the curtains of the tent – the half curtain that remains will hang over at the back of the tabernacle. ²

¹ sn The text seems to describe this part as being in front of the tabernacle, hanging down to form a valence at the entrance (S. R. Driver, Exodus, 284).

² sn U. Cassuto (Exodus, 353) cites b. Shabbat 98b which says, “What did the tabernacle resemble? A woman walking on the street with her train trailing behind her.” In the expression “the half of the curtain that remains,” the verb agrees in gender with the genitive near it.
