Psalms 20:5

(2.) "Let God by his grace keep thee easy from the fear of evil.-- Prov. xviii. 10 , The name of the Lord is a strong tower, into which the righteous run by faith, and are safe; let David be enabled to shelter himself in that strong tower, as he has done many a time." 3.

"We will rejoice in thy salvation." In Jesus there is salvation; it is his own, and hence it is called thy salvation; but it is ours to receive and ours to rejoice in. We should fixedly resolve that come what may, we will rejoice in the saving arm of the Lord Jesus. The people in this psalm, before their king went to battle, felt sure of victory, and therefore began to rejoice beforehand; how much more ought we to do this who have seen the victory completely won! Unbelief begins weeping for the funeral before the man is dead; why should not faith commence piping before the dance of victory begins? Buds are beautiful, and promises not yet fulfilled are worthy to be admired. If joy were more general among the Lord's people, God would be more glorified among men; the happiness of the subjects is the honour of the sovereign. "And in the name of our God we will set up our banners." We lift the standard of defiance in the face of the foe, and wave the flag of victory over the fallen adversary. Some proclaim war in the name of one king, and some of another, but the faithful go to war in Jesu's name, the name of the incarnate God, Immanuel, God with us. The times are evil at present, but so long as Jesus lives and reigns in his church we need not furl our banners in fear, but advance them with sacred courage. Jesu's tremendous name Puts all our foes to flight; Jesus, the meek, the angry Lamb A lion is in fight." The church cannot forget that Jesus is her advocate before the throne, and therefore she sums up the desires already expressed in the short sentence, "The Lord fulfil all thy petitions." Be it never forgotten that among those petitions is that choice one, "Father, I will that they also whom thou hast given me be with me where I am."

We will rejoice in thy salvation - We expect help from thee alone; it is in thy cause we engage; and to thee, as our war is a just one, we consecrate our banners, inscribed with thy name. It is said that the Maccabees had their name from the inscription on their banners; which was taken from Exo 15:11, מי כמכה באלם יהוה mi camochah baelim Yehovah, “Who is like unto thee, O Lord, among the gods?” The word being formed from the initial letters מ M, כ C, ב B, י I, מכבי Ma Ca B I, whence Maccabeus and Maccabees. The words of this verse were spoken by David and his officers; immediately after which I suppose the high priest to have added, The Lord fulfill all thy petitions!

We will rejoice in thy salvation - According to the idea of the psalm suggested in the introduction, this is a response of the king and those associated with him in going forth to battle. It expresses the joy which they would have in the expected deliverance from danger, and their conviction that through his strength they would be able to obtain it. The word salvation here means deliverance; to wit, from the anticipated danger. The phrase implies that God would interpose to save them; it expresses alike their confidence in that, and the fact that such a deliverance would fill their hearts with joy and rejoicing. And in the name of our God - This indicates a sense of dependence on God, and also that the enterprise undertaken was in order to promote his honor and glory. It was not in their own strength, nor was it to promote the purposes of conquest and the ends of ambition; it was that God might be honored, and it was with confidence of success derived from his anticipated aid. We will set up our banners - We will erect our standards; or, as we should say, we will unfurl our flag. All people, when they go to war, have standards or banners, whether flags or some other ensigns, around which they rally; which they follow; under which they fight; and which they feel bound to defend. Each nation has its own standard; but it is difficult to determine what precisely was the form of the standards used among the ancient Hebrews. Military standards, however, were early used (compare Num 1:52; Num 2:2-3, Num 2:10, Num 2:18, Num 2:25; Num 10:14, Num 10:25), and indeed were necessary whenever armies were mustered for war, For the forms of ancient standards, see the article in Kitto’s Cyclopaedia of the Bible, “Standards.” The Lord fulfil all thy petitions - The prayers offered in connection with the sacrifice referred to in Psa 20:3 (compare Psa 20:4).
