Hebrews 2:17-18

Therefore, it was essential that He had to be made like His brothers (mankind) in every respect, so that He might [by experience] become a merciful and faithful High Priest in things related to God, to make atonement (propitiation) for the people’s sins [thereby wiping away the sin, satisfying divine justice, and providing a way of reconciliation between God and mankind]. Because He Himself [in His humanity] has suffered in being tempted, He is able to help and provide immediate assistance to those who are being tempted and exposed to suffering.
