(7) I will declare.--The anointed king now speaks himself, recalling the covenant made with him by Jehovah at his coronation.

I will tell.--Better, Let me speak concerning the appointment. The word rendered decree in our version is derived from a root meaning to engrave, and so stands for any formal agreement, but it is usually an ordinance clearly announced by a prophet or some other commissioned interpreter of the Divine will, and consecrated and legalised by mutual adoption by king and people.

The Lord hath.--Better, Jehovah said unto me: that is, at that particular time, the day which the great event made the new birthday, as it were, of the monarch, or perhaps of the monarchy. From the particular prince, of whose career, if we could identify him with certainty, this would be the noblest historical memorial, the Psalmist--if, indeed, any one historic personage was in his thought at all--let his thoughts and hopes range, as we certainly may, on to a larger and higher fulfilment. The figure of an ideal prince who was always about to appear, but was never realised in any actual successor on the throne, may possibly, by the time of this psalm, have assumed its great place in the nation's prophetic hopes. Certainly the whole line of tradition claims the passage in a Messianic sense. (See Note, Psalm 2:2; and in New Testament Commentary, Note to Acts 13:33; Hebrews 1:5; Hebrews 5:5. For the king, spoken of as God's son, see Psalm 89:26-27, and comp. 2Samuel 7:14.)

Verse 7. - I will declare the decree. It is best to suppose that Messiah here takes the word, and maintains it to the end of ver. 9, when the psalmist resumes in his own person. Messiah "declares," or publishes, a "decree," made by God the Father in the beginning of all things, and communicated by him to the Son, whereby he made known the relationship between them, and invested the Son with sovereign power over the universe. The Lord hath said unto me; rather, said unto me (see the Revised Version). It was said, once for all, at a distant date. Thou art my Son. Not "one of my sons,,' but "my Son;" i.e. my one Son, my only one - "my Son" κατ ἐξοχήν (comp. Psalm 89:27; Hebrews 1:5). This day have I begotten thee. If it be asked, "Which day?" the answer would seem to be, the day when Christ commenced his redemptive work: then the Father "committed all judgment" - "all dominion over creation" to the Son" (John 5:22), gave him, as it were, a new existence, a new sphere, the throne of the world, and of all that is or that ever will be, in it (see 'Speaker's Commentary,' ad loc.).

2:7-9 The kingdom of the Messiah is founded upon an eternal decree of God the Father. This our Lord Jesus often referred to, as what he governed himself by. God hath said unto him, Thou art my Son, and it becomes each of us to say to him, Thou art my Lord, my Sovereign'. The Son, in asking the heathen for his inheritance, desires their happiness in him; so that he pleads for them, ever lives to do so, and is able to save to the uttermost, and he shall have multitudes of willing, loyal subjects, among them. Christians are the possession of the Lord Jesus; they are to him for a name and a praise. God the Father gives them to him, when, by his Spirit and grace, he works upon them to submit to the Lord Jesus.I will declare the decree,.... These are the words of Jehovah's Anointed and King, exercising his kingly office, according to the decree and commandment of the Father: for these words refer not to the following, concerning the generation of the Son, which does not depend on the decree and arbitrary will of God, but is from his nature; but these words relate to what go before. The Septuagint, Vulgate Latin, and Oriental versions, place this clause at the end of Psalm 2:6; some render it, "declaring his commandment", or "the commandment of the Lord"; the laws that he would have observed, both by him and by the subjects of his kingdom. The Syriac and Arabic versions, "that he might declare the commandment of the Lord"; as if this was the end of his being appointed King. The word is differently rendered; by many, "the decree", the purpose of God concerning Christ as Mediator, and the salvation of his people by him; and who so fit to declare this as he who lay in the bosom of the Father, and was privy to all his secret thoughts and designs, and in when the eternal purpose was purposed. John 1:18. The Chaldee paraphrase renders it by "the covenant", the everlasting covenant of grace; and who so proper to declare this as he with whom the covenant was made, and who is the covenant itself, in whom all the blessings and promises of it are, and the messenger of it. Malachi 3:1. It may not be unfitly applied to the Gospel, which is the sum and substance of both the decree and covenant of God; it is what was ordained before the world for our glory. This Christ was appointed to preach, and did declare it in the great congregation; the same with the counsel of God, Acts 20:27. The words will bear to be rendered, "I will declare" "to the command" (h); or according to the order and rule prescribed by Jehovah, without adding to it or taking from it: agreeably to which he executed his office as King, and Prophet also. The doctrine was not his own, but his Father's he preached; he spake not of himself, but as he taught and enjoined him; the Father gave him commandment what he should say and speak, John 12:49; and he kept close to it, as he here says he would: and he ruled in his name, and by his authority, according to the law of his office; and which might be depended upon from the dignity of his person, which qualified him both for his kingly and prophetic offices, expressed in the following words:

the Lord hath said unto me, thou art my Son; not by creation, as angels and men; nor by adoption, as saints; nor by office, as civil magistrates; nor on account of his incarnation or resurrection; nor because of the great love of God unto him; but in such a way of filiation as cannot be said of any creature nor of any other, Hebrews 1:5; He is the true, proper, natural, and eternal Son of God, and as such declared, owned, and acknowledged by Jehovah the Father, as in these words; the foundation of which relation lies in what follows:

this day have I begotten thee; which act of begetting refers not to the nature, nor to the office, but the person of Christ; not to his nature, not to his divine nature, which is common with the Father and Spirit; wherefore if his was begotten, theirs must be also: much less to his human nature, in which he is never said to be begotten, but always to be made, and with respect to which he is without father: nor to his office as Mediator, in which he is not a Son, but a servant; besides, he was a Son previous to his being Prophet, Priest, and King; and his office is not the foundation of his sonship, but his sonship is the foundation of his office; or by which that is supported, and which fits him for the performance of it: but it has respect to his person; for, as in human generation, person begets person, and like begets like, so in divine generation; but care must be taken to remove all imperfection from it, such as divisibility and multiplication of essence, priority and posteriority, dependence, and the like: nor can the "modus" or manner of it be conceived or explained by us. The date of it, "today", designs eternity, as in Isaiah 43:13, which is one continued day, an everlasting now. And this may be applied to any time and case in which Christ is declared to be the Son of God; as at his incarnation, his baptism, and transfiguration upon the mount, and his resurrection from the dead, as it is in Acts 13:33; because then he was declared to be the Son of God with power, Romans 1:4; and to his ascension into heaven, where he was made Lord and Christ, and his divine sonship more manifestly appeared; which seems to be the time and case more especially referred to here, if it be compared with Hebrews 1:3.
