'Open' in the Bible

please let Your ear be attentive and Your eyes open to hear the prayer of Your servant which I am praying before You, day and night, on behalf of Your servants, the sons (descendants) of Israel (Jacob), confessing the sins of the sons of Israel which we have committed against You; I and my father’s house have sinned.

Then Sanballat sent his servant to me in the same way the fifth time, with an open letter in his hand.
