It is said after the people had made a covenant with God,Moses took the blood and sprinkled the book of the covenant,the people,as well as the tabernacle.
Hebrews 9:19 NASB
19 For when every commandment had been spoken by Moses to all the people according to the Law, he took the blood of the calves and the goats, with water and scarlet wool and hyssop, and sprinkled both the book itself and all the people, 20 saying, “This is the blood of the covenant which God commanded you.” 21 And in the same way he sprinkled both the [v]tabernacle and all the vessels of the ministry with the blood.
Though the tabernacle was not dedicated at the same time with the covenant seeing it had not yet been constructed.When it was eventually constructed there is no mention of it being sprinkled with the blood.
Exodus 40:9 NASB
9 Then you shall take the anointing oil and anoint the tabernacle and all that is in it, and shall consecrate it and all its [f]furnishings; and it shall be holy.
So why does the author of the book of Hebrews say the tabernacle was also sprinkled with the blood?
