But one in a certain place testified, saying, What is man, that thou art mindful of him? or the son of man, that thou visitest him?
But - Not unto angels is the Gospel kingdom subjected, "BUT" to MAN.
One ... testified. The usual way of quoting Scripture to readers familiar with it. Psalms 8:5-7 praises Yahweh for exalting MAN, so as to subject all God's works on earth to him. This dignity, lost by the first Adam, is realized only in the Son of man, the Representative Man, Head of our redeemed race. In Hebrews 2:6-8 MAN is spoken of in general ("him ... him ... his"); then, at Hebrews 2:9, first, JESUS is introduced, fulfilling, as man, all the conditions of the prophecy; Himself through death passing, and so bringing us men, His "brethren," to "glory."
What. How insignificant in himself, how exalted by God's grace! (cf. Psalms 144:3.) Enosh and Ben-Adam express man and Son of man in his weakness: "Son of man" is here any and every child of man-unlike the lord of creation which he was originally (Genesis 1:1-31; Genesis 2:1-25), and actually is by title, and shall hereafter fully be in the person of and in union with Jesus, pre-eminently the Son of man (Hebrews 2:9).
Art mindful - as of one absent. Visitest, х episkeptee (G1980)] - lookest after him, as one present.
