Instruction and freedom

God was very detailed about how to build the tabernacle. The type of material and the measurements were very important. Although there was specific instructions, there seemed to be alot of room for creativity. God told them what colors to use in the curtains, yet no design is mentioned (escept the cherubim). This to me shows that God gives us direction but He also allows us to be apart of the process and to be creative in how we carry out his commands.

Who were the "women that served at the entrance to the Tent of Meeting" (38:8)?
