83.53 · Spacial Positions · Above, Below
below a position immediately or directly below a point of orientation, which is often left implicit In a number of languages it is not possible to speak of something ‘below’ without indicating precisely what is involved, but in the case of ACT 2:19 it would be irrelevant to say ‘marvels on the earth below the sky.’ Therefore, one may perhaps most satisfactorily translate this expression in ACT 2:19 as ‘marvels here on the earth.’
