Hath in these {a} last days spoken unto us by his {b} Son, {2} whom he hath appointed {c} heir of all things, by whom also he made the {d} worlds;

(a) So that the former declaration made by the prophets was not complete, and nothing must be added to this latter.

(b) That one Son is God and man.

(2) The second part of the same statement: The same Son is appointed by the Father to be our king and Lord, by whom also he made all things: and in whom only he sets forth his glory, yea and himself also to be under obligation to us, who upholds and supports all things by his will and pleasure.

(c) Possessor and equal partner of all things with the Father.

(d) That is, whatever has been at any time, is, or shall be.

People's New Testament

1:2 Hath in these last days. At the end of these days (Revised Version). At the end of the Jewish dispensation.

Spoken unto us by his Son. Last of all he sent his Son (Mt 27:37). The importance of the message is shown by the messenger. No longer an inspired prophet, but, instead, the Son of God is the speaker.

Whom he hath appointed heir of all things. The Father delivered all things into the hands of the Son (Ac 2:36 Joh 17:10). The heir... is lord of all (Ga 4:1).

By whom also he made the worlds. Through his agency or instrumentality. Christ, the Logos, is represented as God's medium in creation. See PNT Joh 1:3.

Wesley's Notes

1:2 Whom he hath appointed heir of all things - After the name of Son, his inheritance is mentioned. God appointed him the heir long before he made the worlds, Eph 3:11; Prov 8:22, and c. The Son is the firstborn, born before all things: the heir is a term relating to the creation which followed, Heb 1:6. By whom he also made the worlds - Therefore the Son was before all worlds. His glory reaches from everlasting to everlasting, though God spake by him to us only in these last days.

Jamieson-Fausset-Brown Bible Commentary

2. in these last days-In the oldest manuscripts the Greek is. "At the last part of these days." The Rabbins divided the whole of time into "this age," or "world," and "the age to come" (Heb 2:5; 6:5). The days of Messiah were the transition period or "last part of these days" (in contrast to "in times past"), the close of the existing dispensation, and beginning of the final dispensation of which Christ's second coming shall be the crowning consummation.

by his Son-Greek, "IN (His) Son" (Joh 14:10). The true "Prophet" of God. "His majesty is set forth: (1) Absolutely by the very name "Son," and by three glorious predicates, "whom He hath appointed," "by whom He made the worlds," "who sat down on the right hand of the Majesty on high;" thus His course is described from the beginning of all things till he reached the goal (Heb 1:2, 3). (2) Relatively, in comparison with the angels, Heb 1:4; the confirmation of this follows, and the very name "Son" is proved at Heb 1:5; the "heirship," Heb 1:6-9; the "making the worlds," Heb 1:10-12; the "sitting at the right hand" of God, Heb 1:13, 14." His being made heir follows His sonship, and preceded His making the worlds (Pr 8:22, 23; Eph 3:11). As the first begotten, He is heir of the universe (Heb 1:6), which He made instrumentally, Heb 11:3, where "by the Word of God" answers to "by whom"' (the Son of God) here (Joh 1:3). Christ was "appointed" (in God's eternal counsel) to creation as an office; and the universe so created was assigned to Him as a kingdom. He is "heir of all things" by right of creation, and especially by right of redemption. The promise to Abraham that he should be heir of the world had its fulfilment, and will have it still more fully, in Christ (Ro 4:13; Ga 3:16; 4:7).

worlds-the inferior and the superior worlds (Col 1:16). Literally, "ages" with all things and persons belonging to them; the universe, including all space and ages of time, and all material and spiritual existences. The Greek implies, He not only appointed His Son heir of all things before creation, but He also (better than "also He") made by Him the worlds.

Matthew Henry's Concise Commentary

1:1-3 God spake to his ancient people at sundry times, through successive generations, and in divers manners, as he thought proper; sometimes by personal directions, sometimes by dreams, sometimes by visions, sometimes by Divine influences on the minds of the prophets. The gospel revelation is excellent above the former; in that it is a revelation which God has made by his Son. In beholding the power, wisdom, and goodness of the Lord Jesus Christ, we behold the power, wisdom, and goodness of the Father, Joh 14:7; the fulness of the Godhead dwells, not typically, or in a figure, but really, in him. When, on the fall of man, the world was breaking to pieces under the wrath and curse of God, the Son of God, undertaking the work of redemption, sustained it by his almighty power and goodness. From the glory of the person and office of Christ, we proceed to the glory of his grace. The glory of His person and nature, gave to his sufferings such merit as was a full satisfaction to the honour of God, who suffered an infinite injury and affront by the sins of men. We never can be thankful enough that God has in so many ways, and with such increasing clearness, spoken to us fallen sinners concerning salvation. That he should by himself cleanse us from our sins is a wonder of love beyond our utmost powers of admiration, gratitude, and praise.
