Commentary on Exodus 26:1-6

(Read Exodus 26:1-6)

God manifested his presence among the Israelites in a tabernacle or tent, because of their condition in the wilderness. God suits the tokens of his favour, and the gifts of his grace, to his people's state and wants. The curtains of the tabernacle were to be very rich. They were to be embroidered with cherubim, signifying that the angels of God pitch their tents round about the church, Psalm 34:7.
