'Wherein' in the Bible

and the princes of the Philistines come up unto her, and say to her, 'Entice him, and see wherein his great power is, and wherein we are able for him -- and we have bound him to afflict him, and we -- we give to thee, each one, eleven hundred silverlings.'

And Delilah saith unto Samson, 'Declare, I pray thee, to me, wherein thy great power is, and wherewith thou art bound, to afflict thee.'

And she saith unto him, 'How dost thou say, I have loved thee, and thy heart is not with me? these three times thou hast played upon me, and hast not declared to me wherein thy great power is.'
