{Language} (dialekt(9369)). Not a dialect of the Greek, but a
different language, the Aramaic. So also in  2:6  21:40 .
Dialektos is from dialegomai, to converse, to speak between
two (dia). {Akeldama} (Hakeldamach). This Aramaic word Peter
explains as "the field of blood." Two traditions are preserved:
one in  Mt 27:7  which explains that the priests purchased this
potter's field with the money which Judas flung down as the price
of the blood of Jesus. The other in Acts describes it as the
field of blood because Judas poured out his blood there. Hackett
and Knowling argue that both views can be true. "The ill-omened
name could be used with a double emphasis" (Hackett).
