'Open' in the Bible

may your ear be attentive and your eyes be open to hear the prayer of your servant that I am praying to you today throughout both day and night on behalf of your servants the Israelites. I am confessing the sins of the Israelites that we have committed against you -- both I myself and my family have sinned.
