6. But--It is not to angels the Gospel kingdom is subject, BUT . . .
      one . . . testified--the usual way of quoting Scripture to readers familiar with it. Ps 8:5-7 praises Jehovah for exalting MAN, so as to subject all the works of God on earth to him: this dignity having been lost by the first Adam, is realized only in Christ the Son of man, the Representative Man and Head of our redeemed race. Thus Paul proves that it is to MAN, not to angels, that God has subjected the "world to come." In Heb 2:6-8, MAN is spoken of in general ("him . . . him . . . his); then at Heb 2:9, first JESUS is introduced as fulfilling, as man, all the conditions of the prophecy, and passing through death Himself; and so consequently bringing us men, His "brethren," to "glory and honor."
      What, &c.--How insignificant in himself, yet how exalted by God's grace! (Compare Ps 144:3). The Hebrew, "Enosh" and "Ben-Adam," express "man" and "Son of man" in his weakness: "Son of man" is here used of any and every child of man: unlike, seemingly, the lord of creation, such as he was originally (Ge 1:1-2:25), and such as he is designed to be (Ps 8:1-9), and such as he actually is by title and shall hereafter more fully be in the person of, and in union with, Jesus, pre-eminently the Son of man (Heb 2:9).
      art mindful--as of one absent.
      visitest--lookest after him, as one present.
