Thou hast given a banner to them that fear thee, that it may be displayed because of the truth. Selah. Thou hast given a banner - נס nes, a sign, something that was capable of being fixed on a pole.
That it may be displayed - להתנוסס lehithnoses, that it may be unfurled.
Because of the truth - מפני קשט mippeney koshet, from the face of truth; which has been thus paraphrased: If we have displayed the ensign of Israel, and gone forth against these our enemies, who have now made such a terrible breach among us, (Psalms 60:1-3), it was because of thy truth - the promises of victory which we supposed would attend us at all times.
Mr. Mudge, thus: "Thou givest to them that fear thee a signal to be displayed before the truth. That thy favored ones may be delivered, clothe thy right arm with victory, and answer us. God speaketh in his sanctuary, I will exult; I shall portion out Shechem, and measure the valley of Succoth." The fourth verse seems to mean that God had appointed for the consolation of his people a certain signal of favor, with which therefore he prays him to answer them. This, accordingly, he does. God speaketh in his sanctuary, called rybd debir or oracle for that very reason. What he desires then, as he stands imploring the mercy of God before the oracle, is, that he may see the usual signal of favor proceed from it; a voice, perhaps joined with some luminous emanations, whence the phrase of the light of God's countenance. The expression in the sixth verse seems to be proverbial, and means, "I shall divide the spoils of my enemies with as much ease as the sons of Jacob portioned out Shechem, and measured out for their tents the valley of Succoth." Mr. Harmer gives a very ingenious illustration of the giving the banner. "Albertus Aquensis informs us that when Jerusalem was taken in 1099 by the crusaders, about three hundred Saracens got on the roof of a very high building, and earnestly begged for quarter; but could not be induced by any promises of safety to come down, till they had received the banner of Tanered, one of the crusade generals, as a pledge of life. The event showed the faithlessness of these zealots, they put the whole to the sword. But the Saracens surrendering themselves upon the delivering of a standard to them, proves in how strong a light they looked upon the giving a banner, since it induced them to trust it, when they would not trust any promises. Perhaps the delivery of a banner was anciently esteemed in like manner an obligation to protect; and the psalmist might here consider it in this light when he says, Thou hast shown thy people hard things; but thou hast given a banner to them that fear thee. Though thou didst for a time give up thy Israel into the hands of their enemies, thou hast now given them an assurance of thy having received them under thy protection. Thus God gave them a banner or standard that it might be displayed, or lifted up; or rather, that they may lift up a banner to themselves, or encourage themselves with the confident persuasion that they are under the protection of God: because of the truth - the word of promise, which is an assurance of protection - like the giving me and my people a banner, the surest of pledges." - Harmer's Observations.
