God, for whom and through whom everything was made, chose to bring many children into glory. And it was only right that he should make Jesus, through his suffering, a perfect leader, fit to bring them into their salvation.
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.
References for Hebrews 2:11

He also said, “I will put my trust in him,” that is, “I and the children God has given me.”
References for Hebrews 2:13
Because God’s children are human beings—made of flesh and blood—the Son also became flesh and blood. For only as a human being could he die, and only by dying could he break the power of the devil, who had the power of death.
References for Hebrews 2:14
Only in this way could he set free all who have lived their lives as slaves to the fear of dying.
We also know that the Son did not come to help angels; he came to help the descendants of Abraham.
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.
References for Hebrews 2:17
Since he himself has gone through suffering and testing, he is able to help us when we are being tested.
