'Be Glad and Rejoice' in the Bible

And it shall be said in that day, Behold, this is our God; we have waited for him, and he will save us: this is Jehovah, we have waited for him; we will be glad and rejoice in his salvation.

But be glad and rejoice for ever in that which I create. For behold, I create Jerusalem a rejoicing, and her people a joy.
