Revelation 15:5,6 - The temple in heaven was opened

15:5

NIV has “I saw in heaven the temple - that is, the tabernacle of the covenant law”. ESV, and others, have “the sanctuary of the tent of witness in heaven”. ESV is probably more accurate, but whatever the case it seems to be pointing to the tabernacle in the Exodus. The tabernacle was opened.

15:6

Out of the tabernacle came the seven angels with the seven plagues. So these plagues are not just things that happened, they were deliberately delivered to the earth by God. They were a divine act. The angels were dressed in clean, shining linen and wore golden sashes. These were “good” angels, not demons. Emphasising again the divine nature of the acts, they are a deliberate and righteous part of God’s plan.
