{Amazement came} (egeneto thambos). Mark has
ethamb(8874)h(8873)an. {They spake together one with another}
(sunelaloun pros all(886c)ous). Imperfect indicative active and the
reciprocal pronoun. Mark has simply the infinitive sunz(8874)ein
(question). {For} (hoti). We have here an ambiguous hoti as
in  1:45 , which can be either the relative "that" or the casual
hoti "because" or "for," as the Revised Version has it. Either
makes good sense. Luke adds here dunamei (with power) to Mark's
"authority" (exousian). {And they come out} (exerchontai). So
Luke where Mark has "and they obey him" (kai upakouousin
aut(9369)).
