Charles H. Spurgeon on Psalms 119:43

Take not the word of truth, etc. It is well known that men do, when persecution threatens, either altogether deny the truth, or weakly and lukewarmly confess it; but lest this should happen to him, David therefore prays here, O Lord, take not the word of truth utterly out of my mouth, i.e., make me, with an intrepid spirit, always to confess the avowed truth boldly and manfully. In the Hebrew text it is dak de, "very, ""very much, "or, as Augustine renders it, "wholly and altogether"; and he thinks that David prayed for this, that, if through human weakness it should happen to him to fall, and at some time or other not steadfastly to confess the word, yet that God would not allow him to continue in that sit, , but again restore and establish him; and he illustrates this by the example of Peter. Further, David adds the reason which has impelled him thus to pray: Because I have for, and even with great desire, as the Hebrew verb lhy signifies, "thy judgments, " with which in the last day thou wilt openly pass sentence on heretics, fanatics, and all tyrants. Solomon Gesner.
