2:8 humbled himself. He not only stooped from the glory of heaven’s throne to become a true human being, yet sinless, but He also became like a bondservant and finally like a guilty criminal, condemned to die, even(!) to die in what has been said to be the most excruciatingly painful death conceivable, that of crucifixion. His obedience all through His life culminated in this ultimate act of obedience (note Hebrews 5:8), and it was all for us!
2:9 highly exalted him. Following His death and triumphant visit to Hades (“the things under the earth”—see notes on I Peter 3:19-20), He rose from the dead, ascended to heaven and assumed “all power in heaven and in earth” (Matthew 28:18).
2:9 a name. Literally, “the name.”
