'Discovered' in the Bible

When I would have healed Israel, then the iniquity of Ephraim was discovered, and the wickedness of Samaria: for they commit falsehood; and the thief cometh in, and the troop of robbers spoileth without.

I discovered Israellike grapes in the wilderness.I saw your fatherslike the first fruit of the fig tree in its first season.But they went to Baal-peor,consecrated themselves to Shame,and became detestable,like the thing they loved.
