The fifth song of the Hallel is addressed to all peoples. They are called upon to praise and laud The LORD because His truth endureth for ever. In the long process of the centuries Israel never fully realised this ideal. At last the purpose was consummated in a Person. All the ancient prophecies found in Him their potential fulfilment.
In that upper room the song was a solo as to actual experience. By the union of grace and truth, in and through Jesus, the call to praise went out to all nations and peoples. Those who joined Him in the song that night were made able to sing in following days with meaning and with force; and that is the song with which the Redeemed have gone forth ever since to woo and win the peoples to The LORD.
