“are glad.” The Hebrew is sameach (#08056 שָׂמֵ֫חַ), and means to take pleasure in something, to be glad, to be merry. It is often translated as “joyful,” or a related “joy” word, but biblically, joy comes from inside a person due to eternal verities such as our Hope. Therefore, glad, merry, pleasure, jubilation, etc., are better translations.
