'Hope' in the Bible

And Asa made prayer to the Lord his God and said, Lord, you only are able to give help against the strong to him who has no strength; come to our help, O Lord our God, for our hope is in you, and in your name we have come out against this great army. O Lord, you are our God; let not man's power be greater than yours.

Sennacherib, king of Assyria, says, In what are you placing your hope, waiting here in the walled town of Jerusalem?
