'Proper' in the Bible

and it became known to all those dwelling in Jerusalem, insomuch that that place is called, in their proper dialect, Aceldama, that is, field of blood,

to receive the share of this ministration and apostleship, from which Judas, by transgression, did fall, to go on to his proper place;'

and the rumour of this having come, the multitude came together, and was confounded, because they were each one hearing them speaking in his proper dialect,

and how do we hear, each in our proper dialect, in which we were born?
