{Commanded} (prosetaxen). First aorist active indicative.
Peter himself abstained from baptizing on this occasion (cf. Paul
in  1Co 1:14 ). Evidently it was done by the six Jewish brethren.
{Them to be baptized} (autous baptisth(886e)ai). Accusative of
general reference with the first aorist passive infinitive. {In
the name of Jesus Christ} (en t(9369) onomati I(8873)ou Christou). The
essential name in Christian baptism as in  2:38  19:5 . But these
passages give the authority for the act, not the formula that was
employed (Alvah Hovey in Hackett's _Commentary_. See also chapter
on the Baptismal Formula in my _The Christ of the Logia_).
"Golden days" (aurei dies, Bengel) were these for the whole
group.
