2:6 in a certain place. This passage, quoted from Psalm 8:4-5, confirms that the eighth psalm is indeed a prophetic psalm of the Messiah.

2:7 lower than the angels. See also Hebrews 2:9. The Son of God became Jesus, Son of man, by divine incarnation (Hebrews 2:14-16). He who was “better than the angels” (Hebrews 1:4) was made a “little [that is, “for a little time”—thirty-three years] lower than the angels.” He who was the divine Word became flesh (John 1:14); He who was “equal with God” became “a servant” (Philippians 2:7).

2:7 glory and honour. Because, in His incarnation, He was “obedient unto death,” He has been given the “name which is above every name” (Philippians 2:8-9).

2:8 under his feet. Even the angels are to be in subjection to man (Hebrews 1:14; 2:8; I Corinthians 6:3). The first man, Adam, was given dominion over the earth and all its creatures (Genesis 1:26-28), but sin intervened and it remains for the Son of man, “the last Adam” (I Corinthians 15:45) to regain man’s lost dominion.

2:8 all in subjection. Jesus, as the perfect man and as Son of man, at times even during His first coming exercised His future dominion over the earth (e.g., Mark 4:41; Matthew 17:27). This was just a prophetic foreshadowing and evidence that He will exercise man’s dominion in all its fullness in the age to come. First, however, He had to purge our sins and eventually remove the great curse from the earth.

2:9 for every man. Note that Jesus did not die merely for “the sin of the world” (John 1:29), but for “every man” individually. Furthermore, as Paul says, Christ “loved me, and gave Himself for me” (Galatians 2:20)!
