If He didn't then how could this be true?:
Therefore, it was necessary for him to be made in every respect like us, his brothers and sisters, so that he could be our merciful and faithful High Priest before God. Then he could offer a sacrifice that would take away the sins of the people. Since he himself has gone through suffering and testing, he is able to help us when we are being tested.
Hebrews 2:17-18 NLT
https://bible.com/bible/116/heb.2.17-18.NLT
you do have to take what was said prior to Heb 2:17-18 if you do not then it is confusing
So if you read hebrews chapter 1
this is said first about Jesus so we should I think Build on this from Chapter 1 moving through the book of Hebrews
NLT:
:1
Long ago God spoke many times and in many ways to our ancestors through the prophets.
:2
And now in these final days, he has spoken to us through his Son. G
:3
The Son radiates God’s own glory and expresses the very character of God, he sustains everything by the mighty power of his command. When he had cleansed us from our sins, he sat down in the place of honor at the right hand of the majestic God in heaven.
:4
This shows that the Son is far greater than the angels, just as the name God gave him is greater than their names.
:5
For God never said to any angel what he said to Jesus:
“You are my Son.
Today I have become your Father.[fn]”God also said,
“I will be his Father,
and he will be my Son.”[fn]
:6
And when he brought his supreme[fn] Son into the world, God said,[fn]
“Let all of God’s angels worship him.”[fn]
Please read on to Heb 21-18
From chapter one
Jesus is very much seen as God Here & our High Priest which has to be without sin.
Hews 1 says Jesus has or is the following :
God promised everything to the Son as an inheritance, and
through the Son he created the universe.
Jesus in Creation= had to be without sin
The Son radiates
God’s own glory and expresses the very character of God, = had to be without SIN to have the VERY Character of God.
This shows
that the Son is far greater than the angels, just
as the name God gave him is greater than their names.
the name is "authority " God gave HIM greater= could not be done if HE had sin
nd on and on it goes.
SO what is it in Heb 2:17-18 ?
If we look at verse 1 of chapter two It tells us to do what?
:1
So we must listen very carefully to
the truth we have heard, or we may drift away from it.
this is in context to what has already be said bout Jesus in chapter 1
Jesus when HE said in verse 11
So now Jesus and the ones he makes holy have the same Father. That is why Jesus is not ashamed to call them his brothers and sisters.[fn]
who are the brothers and sisters it is speaking about in 17 -18?
The Jews .
