5. For--substantiating His having "obtained a more excellent name than the angels."
      unto which--A frequent argument in this Epistle is derived from the silence of Scripture (Heb 1:13; Heb 2:16; 7:3, 14) [BENGEL].
      this day have I begotten thee-- (Ps 2:7). Fulfilled at the resurrection of Jesus, whereby the Father "declared," that is, made manifest His divine Sonship, heretofore veiled by His humiliation (Ac 13:33; Ro 1:4). Christ has a fourfold right to the title "Son of God"; (1) By generation, as begotten of God; (2) By commission, as sent by God; (3) By resurrection, as "the first-begotten of the dead" (compare Lu 20:36; Ro 1:4; Re 1:5); (4) By actual possession, as heir of all [BISHOP PEARSON]. The Psalm here quoted applied primarily in a less full sense to Solomon, of whom God promised by Nathan to David. "I will be his father and he shall be my son." But as the whole theocracy was of Messianic import, the triumph of David over Hadadezer and neighboring kings (2Sa 8:1-18; Ps 2:2, 3, 9-12) is a type of God's ultimately subduing all enemies under His Son, whom He sets (Hebrew, "anointed," Ps 2:6) on His "holy hill of Zion," as King of the Jews and of the whole earth. the antitype to Solomon, son of David. The "I" in Greek is emphatic; I the Everlasting Father have begotten Thee this day, that is, on this day, the day of Thy being manifested as My Son, "the first-begotten of the dead" (Col 1:18; Re 1:5). when Thou hast ransomed and opened heaven to Thy people. He had been always Son, but now first was manifested as such in His once humbled, now exalted manhood united to His Godhead. ALFORD refers "this day" to the eternal generation of the Son: the day in which the Son was begotten by the Father is an everlasting to-day: there never was a yesterday or past time to Him, nor a to-morrow or future time: "Nothing there is to come, and nothing past, but an eternal NOW doth ever last" (Pr 30:4; Joh 10:30, 38; 16:28; 17:8). The communication of the divine essence in its fulness, involves eternal generation; for the divine essence has no beginning. But the context refers to a definite point of time, namely, that of His having entered on the inheritance (Heb 1:4). The "bringing the first-begotten into the world" (Heb 1:6), is not subsequent, as ALFORD thinks, to Heb 1:5, but anterior to it (compare Ac 2:30-35).
