Aaron shall make atonement on its horns once a year. With the blood of the sin offering of atonement he shall make atonement for it once in the year throughout your generations. It is most holy to YHWH.
#exodus 30:10

#Yeshua's blood is sufficient to atone for all our sins before God for eternal salvation, but ongoing repentance and atonement still aids the state of our heart and the acceptability of our worship and prayers to God.
