Every high priest is chosen from his fellow-men and appointed to serve God on their behalf, to offer sacrifices and offerings for sins.
Since he himself is weak in many ways, he is able to be gentle with those who are ignorant and make mistakes.
And because he is himself weak, he must offer sacrifices not only for the sins of the people but also for his own sins. 1
References for Hebrews 5:3

But even though he was God's Son, he learned through his sufferings to be obedient.
When he was made perfect, he became the source of eternal salvation for all those who obey him,
and God declared him to be high priest, in the priestly order of Melchizedek.

There is much we have to say about this matter, but it is hard to explain to you, because you are so slow to understand.
There has been enough time for you to be teachers - yet you still need someone to teach you the first lessons of God's message. Instead of eating solid food, you still have to drink milk. 6
References for Hebrews 5:12
5.12, 13 1 Co 3.2.
Anyone who has to drink milk is still a child, without any experience in the matter of right and wrong.
Solid food, on the other hand, is for adults, who through practice are able to distinguish between good and evil.
