Malachi 3.1-4
Thus says the Lord God: “See, I am sending my messenger to prepare the way before me, and the Lord whom you seek will suddenly come to his temple. The messenger of the covenant in whom you delight — indeed, he is coming,” says the Lord of hosts.
“But who can endure the day of his coming, and who can stand when he appears? For he is like a refiner’s fire and like fullers’ soap; he will sit as a refiner and purifier of silver, and he will purify the sons of Levi and refine them like gold and silver, until they present offerings to the Lord in righteousness. Then the offering of Judah and Jerusalem will be pleasing to the Lord as in the days of old and as in former years.”

Hebrews 2.10-11, 13b-18
It was fitting that God, for whom and through whom all things exist, in bringing many sons and daughters to glory, should make the source of their salvation perfect through sufferings. For the one who sanctifies and those who are sanctified are all from one.
For this reason he is not ashamed to call them brothers and sisters, saying, “Here am I, and the children whom God has given me.” Since the children share flesh and blood, Jesus himself likewise shared the same things, so that through death he might destroy the one who has the power of death, that is, the devil, and free those who all their lives were held in slavery by the fear of death.
For it is clear that Jesus did not come to help Angels, but the descendants of Abraham. Therefore he had to become like his brothers and sisters in every respect, so that he might be a merciful and faithful high priest in the service of God, to make a sacrifice of atonement for the sins of the people.
Because Jesus himself was tested by what he suffered, he is able to help those who are being tested.
