This verb means to explain or clarify something thoroughly, making obscure matters plain. Matthew uses it twice in his Gospel: Jesus' disciples asking him to 'explain' the parable of the weeds (13:36), and the servants reporting clearly to their master about the unforgiving servant's actions (18:31). The compound suggests 'making clear through and through,' removing ambiguity or obscurity. The term appears in contexts requiring detailed explanation or clear reporting. Spanish 'Explícanos' (Explain to us) and 'declararon' (they explained) directly capture this sense of clarification, while German 'Διασάφησον' preserves the request for clear understanding.
