Hebrews 4:14 describes Jesus as the high priest. I'm this verse he also describes Jesus as the Son of God.
By describing Jesus in this way, the writer of the passage aims to show that Jesus is more important and has more authority than the other Jewish priets. This description is proven by the continued attempts to tempt Jesus but he never gave into the temptations.
