gives cause and matter for high and lasting joy, by making Himself known also to the church, in which He has taken up His abode, in deeds of mercy (loving-kindness or grace). There (שׁם, Psa 133:3) in Zion is indeed the kingship of promise, which cannot fail of fulfilment. He will cause a horn to shoot forth, He will prepare a lamp, for the house of David, which David here represents as being its ancestor and the anointed one of God reigning at that time; and all who hostilely rise up against David in his seed, He will cover with shame as with a garment (Job 8:22), and the crown consecrated by promise, which the seed of David wears, shall blossom like an unfading wreath. The horn is an emblem of defensive might and victorious dominion, and the lamp (נר, 2Sa 21:17, cf. ניר, 2Ch 21:7, lxx λύχνον) an emblem of brilliant dignity and joyfulness. In view of Eze 29:21, of the predictions concerning the Branch (zemach) in Isa 4:2; Jer 23:5; Jer 33:15; Zec 3:8; Zec 6:12 (cf. Heb 7:14), and of the fifteenth Beracha of the Shemone - Esre (the daily Jewish prayer consisting of eighteen benedictions): “make the branch (zemach) of David Thy servant to shoot forth speedily, and let his horn rise high by virtue of Thy salvation,” - it is hardly to be doubted that the poet attached a Messianic meaning to this promise. With reference to our Psalm, Zacharias, the father of John the Baptist, changes that supplicatory beracha of his nation (Luk 1:68-70) into a praiseful one, joyfully anticipating the fulfilment that is at hand in Jesus.
