Job 1:6 - Matthew Poole's English Annotations on the Holy Bible

There was a day, i.e. a certain time appointed by God. The sons of God, i.e. the holy angels, so called Job 38:7 Daniel 3:25,28, because of their creation by God, as Adam also was, Luke 3:38, and for their great resemblance of him in power, and dignity, and holiness, and for their filial affection and obedience to him. Before the Lord, i.e. before his throne, to receive his commands, and to give him an account of their negotiations. Compare 1 Kings 22:19 Malachi 4:14 Luke 1:19. But you must not think that these things were really done, and that Satan was mixed with the holy angels, or admitted into the presence of God in heaven, to maintain such discourses as this with the blessed God, or that he had formal commission and leave to do what follows; but it is only a parabolical representation of that great truth, that God by his wise and holy providence doth govern all the actions of men and devils to his own ends; it being usual with the great God to condescend to our shallow capacities, and to express himself, as the Jews phrase it, in the language of the sons of men, i.e. in such manner as men use to speak and may understand. Satan came also among them; being forced to come, and give up his account.
