'Searching' in the Bible

And I say to you, Make requests, and they will be answered; what you are searching for, you will get; when you give the sign, the door will be open to you.

For to everyone who makes a request, it will be given; and he who is searching will get his desire; and to him who gives the sign, the door will be open.

Or what woman, having ten bits of silver, if one bit has gone from her hands, will not get a light, and go through her house, searching with care till she sees it?
