'Behalf' in the Bible

Moses, Aaron, and his sons, who performed the duties of the sanctuary as a service on behalf of the Israelites, camped in front of the tabernacle on the east, in front of the tent of meeting toward the sunrise. Any unauthorized person who came near it was to be put to death.

The priest is to offer one as a sin offering and the other as a burnt offering to make atonement on behalf of the Nazirite, since he sinned because of the corpse. On that day he must consecrate his head again.

From the Israelites, I have given the Levites exclusively to Aaron and his sons to perform the work for the Israelites at the tent of meeting and to make atonement on their behalf, so that no plague will come against the Israelites when they approach the sanctuary.”

The priest must then make atonement before the Lord on behalf of the person who acts in error sinning unintentionally, and when he makes atonement for him, he will be forgiven.
