Who have received the law - The Law of Moses, given on Mount Sinai.
By the disposition of angels - There has been much diversity of opinion in regard to this phrase, εἰς διαταγὰς ἀγγέλων eis diatagas angelōn. The word translated “disposition” does not occur elsewhere in the New Testament. It properly means the “constituting” or “arranging” of an army; disposing it into ranks and proper divisions. Hence, it has been supposed to mean that the Law was given “amidst” the various ranks of angels, being present to witness its promulgation. Others suppose that the angels were employed as agents or instruments to communicate the Law. All that the expression fairly implies is the former; that the Law was given amidst the attending ranks of angels, as if they were summoned to witness the pomp and ceremony of giving “law” to an entire people, and through them to an entire world. It should be added, moreover, that the Jews applied the word “angels” to any messengers of God; to fire, and tempest, and wind, etc. And all that Stephen means here may be to express the common Jewish opinion that God was attended on this occasion by the heavenly hosts, and by the symbols of his presence, fire, and smoke, and tempest. Compare Psalms 104:4; Psalms 68:17. Other places declare that the Law was spoken by an angel, one eminent above all attending angels, the special messenger of God. See the notes on Acts 7:38. It is plain that Stephen spoke only the common sentiment of the Jews. Thus, Herod is introduced by Josephus (Antiq., book 15, chapter 5, section 3) as saying, “We have learned in God the most excellent of our doctrines, and the most holy part of our Law by angels,” etc. In the eyes of the Jews, it justly gave increased majesty and solemnity to the Law, that it had been given in so grand and imposing circumstances. It greatly aggravated their guilt that, notwithstanding this, they had not kept it.
