'Joyful' in the Bible

"This is what the LORD of the Heavenly Armies says: "The fasts that occur in the fourth, fifth, seventh, and tenth months will be joyful and glad times for the house of Judah, replete with cheerful festivals. Therefore, love truth and peace.'"

And they of Ephraim shall be like a mighty man, and their hearts shall rejoice as through wine; and their children shall see it, and rejoice; their heart shall be joyful in Jehovah.
