Psalms 20:5

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 Numbers 1:52; Numbers 2:2, Numbers 2:10, Numbers 2:18, Numbers 2:25; Numbers 10:14, Numbers 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 Psalms 20:3 (compare Psalms 20:4). This, according to the view suggested in the introduction, is the response of the people, expressing their desire that the king might be successful in what he had undertaken, and that the prayers which had been offered for success might be answered.
