ISB ~ Hebrews 10 v22

draw near:i.e., into the presence of God, who sits enthroned in the innermost chamber of heaven (4:16). Believers draw near for prayer and worship, as the Israelites did in coming to the Mosaic Tabernacle (10:1). hearts sprinkled …

bodies washed:An allusion to Baptism. Its waters make outward contact with the body but effect an inward cleansing of the heart (Acts 22:16; Eph 5:26; 1 Pet 3:21).

• Sprinkling with blood and washing with water are liturgical rites associated with the ordination of Aaronic priests (Ex 29:4, 21; Lev 8:6, 30). In a similar way, Baptism consecrates us into the universal priesthood of believers (1 Pet 2:9; Rev 1:5-6). This qualifies us to enter the heavenly Tabernacle (Heb 10:19) and enables us to make pleasing sacrifices to the Lord (13:15-16) (CCC 1268).
