'Proved' in the Bible

by this ye are proved: Pharaoh liveth! if ye go out from this -- except by your young brother coming hither;

send one of you, and let him bring your brother, and ye, remain ye bound, and let your words be proved, whether truth be with you: and if not -- Pharaoh liveth! surely ye are spies;'

Thou hast proved my heart, Thou hast inspected by night, Thou hast tried me, Thou findest nothing; My thoughts pass not over my mouth.

Where your fathers have tried Me, Have proved Me, yea, have seen My work.
