And Saul yet breathing out threatenings and slaughter,.... The historian having given an account of the dispersion of all the preachers of the Gospel at Jerusalem, excepting the apostles, and of their success in other parts, especially of Philip's, returns to the history of Saul; who, not satisfied with the murder of Stephen, and with the havoc he made of the church at Jerusalem, haling them out of their houses to prison, continued not only to threaten them with confiscation of goods and imprisonment, but with death itself.
The phrase here used is an Hebraism; so in Ps 27:12 omx xpy, "one that breathes out violence", or cruelty; and this shows the inward disposition of his mind, the rage, wrath, malice, envy, and blood thirstiness he was full of; and is observed to illustrate the riches of divine grace in his conversion.
And wonderful it is, that that same mouth which breathed out destruction and death to the followers of Christ, should afterwards publish and proclaim the Gospel of the grace of God; that he whose mouth was full of cursing and bitterness, should hereafter, and so very quickly, come forth in the fulness of the blessing of the Gospel of Christ.
