Matthew Poole and continuators on Acts 22:23

23 And as they cried out, and cast off their clothes, and threw dust into the air,

They that stoned the Blasphemer, cast off their upper garments, that they might be the readier to do that Execution, and carry the heavier stones; as Chap. 7.58. They might also cast, or rend them off in sign of grief and detestation of Paul's (supposed) Blasphemy.

Out of raging madness, having no stones at present in that place to throw at him; or stamping on the ground first with their feet, and taking thence the loosn[illegible: 1 letter]d Earth, threw it up, to shew that Paul had sinned against Heaven, and provoked the God who dwells there: And that he was not worthy to tread on the Earth; which as well as they could, they took from him.
