In ancient Israel, the high priest had the solemn duty of entering the Most Holy Place, where the Ark of the Covenant was kept, only once a year on the Day of Atonement. This verse outlines a crucial part of that ritual: the burning of incense. The incense, when placed on the fire, produces smoke that fills the space, concealing the atonement cover, or mercy seat, which is above the Ark. This smoke acts as a protective veil, shielding the priest from the direct presence of God, which was considered too holy to be seen by human eyes.
The ritual underscores the seriousness and sanctity of approaching God, reminding us of the need for humility and reverence in worship. It also reflects the belief that God's presence is both life-giving and overwhelming, requiring careful preparation and respect. This practice is a vivid reminder of the holiness of God and the importance of following divine instructions to maintain a right relationship with Him. It encourages believers to approach God with awe and respect, recognizing His majesty and the sacredness of His presence.
