Exodus 30:10

And Aaron shall make an atonement vpon the hornes of it once in a yeere, with the blood of the sinne offering of atonements: once in the yeere shall hee make atonement vpon it, throughout your generations: it is most holy vnto the Lord. Exodus 30:10 (KJV)

The instruction concerns the altar of incense, a small gold‑covered altar placed inside the Holy Place, just before the veil that separated it from the Most Holy Place where the Ark of the Covenant resided. Aaron, the high priest, was responsible for making atonement upon the horns of this altar once each year with the blood of the sin offering. The horns were the protruding corners at the top of the altar, and the blood was applied there as a means of covering sin.

Atonement is a central biblical concept that denotes reconciling or making amends for sin. In the Old Testament the shedding of blood symbolized the cost of sin and the need for forgiveness. Various offerings and sacrifices were prescribed to make atonement for the people, and the blood of those sacrifices served as a covering, symbolically cleansing before God.

The high priest’s role in this ritual highlighted the seriousness of the covenant relationship. By applying the blood of the sin offering to the altar’s horns, Aaron enacted the yearly reminder of the continual need for atonement. This annual observance, commanded to be performed “once in the year” throughout generations, underscored the ongoing relationship between God and His people.

Although the bronze altar of burnt offering stood outside the Tabernacle, the verse in question does not pertain to that altar but to the altar of incense within the sanctuary. Both altars were regarded as holy because they mediated worship, yet the altar of incense is described as “most holy unto the LORD.”

Application for believers today points to the ultimate atoning sacrifice of Jesus Christ. While the Old Testament rites are not observed in the same manner, the principle of atonement and the need for forgiveness remain relevant. Christians are called to acknowledge sin, seek God’s forgiveness, and trust in the atoning work of Christ, whose blood cleanses us from all unrighteousness (1 John 1:7). Maintaining the holiness of our relationship with God involves dedicating our lives to Him and avoiding anything that would defile that connection.

In conclusion, Exodus 30:10 reminds us of the importance of atonement, the role of the high priest, and the significance of holiness in our relationship with God. Through Christ’s sacrifice we experience true forgiveness and can draw near to God with gratitude and reverence.
