Charles H. Spurgeon on Psalms 101:3

Wicked thing. The original hath it, if we will render it word for word, "I will set no word of Belial before mine eyes." But word is figuratively there put for thing; as likewise Ps 41:8; and so is it rendered both by Montanus in the margin, and in the text by Junius; howbeit, in his comment upon this psalm, he precisely follows the original, applying it against sycophants and flatterers, the mice and moths of court. —George Hakewill.
