A.T. Robertson Commentary Hebrews 9:21

"Moreover the tabernacle and all the vessels of the ministry he sprinkled in like manner with the blood." — Hebrews 9:21 (ASV)

In like manner with the blood (τω αιματ ομοιως). Instrumental case of αιμα (blood). But the use of the article does not necessarily refer to the blood mentioned in verse 19. In Ex 40:9 Moses sprinkled the tabernacle with oil. It had not been erected at the time of Ex 24:5f. Josephus (Ant. III. 8, 6) gives a tradition that blood was used also at this dedication. Blood was used annually in the cleansing rites on the day of atonement.
