Leviticus 4:26ESV·traditional attribution

And all its fat he shall burn on the altar, like the fat of the sacrifice of peace offerings. So the priest shall make atonement for him for his sin, and he shall be forgiven.

Matthew Henry Presbyterian @wholebiblehenry

Observe here, 1. That God takes notice of and is displeased with the sins of rulers. Those who have power to call others to account are themselves accountable to the ruler of rulers; for, as high as they are, there is a higher than they. This is intimated in that the commandment transgressed is here said to be the commandment of the Lord his God, Lev 4:22.

And if anyone of the common people sin through ignorance,.... Or, "if one soul of the people of the earth": that is, a single person, and so is distinguished from the congregation, one of the common sort of people; however is neither an high priest, nor a prince, or king, but either a common priest, or Levite, or Israelite; no man is free from sin...

SIN OFFERING FOR THE PRIEST. (Lev. 4:3-35) If the priest that is anointed do sin--that is, the high priest, in whom, considering his character as typical mediator, and his exalted office, the people had the deepest interest; and whose transgression of any part of the divine law, therefore, whether done unconsciously or heedlessly, was a very serious offense, both as regarded himself individually, and the influence of his example.
