Albert Barnes on Acts 8:2

And devout men. Religious men. The word used here does not imply of necessity that they were Christians. There might have been Jews who did not approve the popular tumult, and the murder of Stephen, and who gave him a decent burial. Joseph of Arimathaea, and Nicodemus, both Jews, thus gave to the Lord Jesus a decent burial, Jn 19:38,39.

Carried Stephen. The word translated carried means, properly, to collect, as fruits, etc. Then it is applied to all the preparations necessary for fitting a dead body for burial--as collecting, or confining it by bandages, with spices, etc.

And made great lamentation. This was usual among the Jews at a funeral. Mt 9:23.
