'Uncovered' in the Bible

and Jehovah had uncovered the ear of Samuel one day before the coming of Saul, saying,

And Jonathan saith unto David, 'Jehovah, God of Israel -- when I search my father, about this time to-morrow or the third day, and lo, good is towards David, and I do not then send unto thee, and have uncovered thine ear --

thus doth Jehovah do to Jonathan, and thus doth He add; when the evil concerning thee is good to my father, then I have uncovered thine ear, and sent thee away, and thou hast gone in peace, and Jehovah is with thee, as he was with my father;

And the king saith to runners, those standing by him, 'Turn round, and put to death the priests of Jehovah, because their hand also is with David, and because they have known that he is fleeing, and have not uncovered mine ear;' and the servants of the king have not been willing to put forth their hand to come against the priests of Jehovah.
