      37. made an hanging for the . . . door--Curtains of elaborately wrought needlework are often suspended over the entrance to tents of the great nomad sheiks, and throughout Persia, at the entrance of summer tents, mosques, and palaces. They are preferred as cooler and more elegant than wooden doors. This chapter contains an instructive narrative: it is the first instance of donations made for the worship of God, given from the wages of the people's sufferings and toils. They were acceptable to God (Php 4:18), and if the Israelites showed such liberality, how much more should those whose privilege it is to live under the Christian dispensation (1Co 6:20; 16:2).
