Where in the bible it say unspeakable joy?

The phrase "unspeakable joy" is found in 1 Peter 1:8, which states, "Though you have not seen him, you love him; and even though you do not see him now, you believe in him and are filled with an inexpressible and glorious joy." This verse emphasizes the deep, profound joy that comes from faith in Christ, even in the absence of physical evidence.
