Hebrews 2:13; (Isaiah 8:17-18)

And again,
“I will put my trust in him.”
And again,
“Behold, I and the children God has given me.”
(Hebrews 2:13 ESV)

This is a reference to the Messiah speaking, as a man, placing his hope, his only hope in God. Jesus identifies himself with the people--fully man. "I will look to him; I will put my confidence in him." And this relationship Jesus has with His people is the same closeness a father has with his children. They were of one family; one nature. He identifies with man.
