The king sent and loosed him
That is, Pharaoh king of Egypt sent messengers to the prison, and ordered Joseph to be loosed, as soon as ever he heard the account which the chief butler gave of him, and of his skill in interpreting dreams.
Even the ruler of the people;
or "peoples": the subjects of Pharaoh's kingdom being very numerous.
And let him go free,
ordered his fetters to be taken off, and him to be set at liberty, to go where he pleased; or, however, that he might come to court, whither he was brought, and which was the end of his releasement; see ( Genesis 41:14 ) , in this he was a type of Christ in his resurrection from the dead; who for a while was under the dominion of death, was held with the pains and cords of it, and was under the power and in the prison of the grave; but it was not possible, considering the dignity of his person, and the performance of his work as a surety, that he should be held here. Wherefore the cords and pains of death were loosed, and he was brought out of prison; God his Father, the King of kings, sent an angel from heaven, to roll away the stone of the sepulchre, and let the prisoner free; so that he was legally and judicially discharged and acquitted; as it was proper he should, having satisfied both law and justice; he was justified in the Spirit when he rose from the dead, and all his people were justified in him, for he rose again for their justification.
