4.

Because they have seen, then, "Make a joyful noise unto the Lord, all ye lands" (ver. 4). Ye already know what it is to make a joyful noise. Rejoice, and speak. If ye cannot express your joy, shout ye; let the shout manifest your joy, if your speech cannot: yet let not joy be mute; let not your heart be silent respecting its God, let it not be mute concerning His gifts. If thou speakest to thyself, unto thyself art thou healed; if His right hand hath healed thee for Him, speak thou unto Him for whom thou hast been healed. "Sing, rejoice, and make melody."
