The cherubim of divine glory were angel statues on the cover of the ark. These angels are closely linked to God's glorious presence (Genesis 3:24; Psalms 80:1; 99:1; Isaiah 37:16). The ark's cover was the atonement place, where they sprinkled blood from the Day of Atonement sacrifice (Leviticus 16:14–16).
we cannot discuss these things in detail now: The main topic is the offering of sacrifices under the old covenant (Hebrews 9:6–10).
