Ver. 20 presents difficulties. The word rendered in the A.V. and R.V. (text) "speak against Thee" is peculiarly spelt if this is its meaning, and its construction is anomalous. Probably, therefore, the rendering should be as above. That meaning does not require a change of consonants, but only of vowel points. The difficulty of the last clause lies mainly in the word translated in the A.V. _adversaries_ and in the R.V. "_enemies_." That meaning is questionable; and if the word is the nominative to the verb in the clause, the construction is awkward, since the preceding "who" would naturally extend its influence to this clause. Textual emendation has been resorted to; the simplest form of which is to read "against Thee" for "Thine adversaries," a change of one letter. Another form of emendation, which is adopted by Cheyne and Graetz, substitutes "Thy name," and reads the whole, "And pronounce Thy name for falsehoods." Delitzsch adheres to the reading "adversaries," and by a harsh ellipsis makes the whole to run, "Who pronounce [Thy name] deceitfully--Thine adversaries." The vindication of the psalmist's indignation lies in vv. 21, 22. That soul must glow with fervent love to God which feels wrong done to His majesty with as keen a pain as if it were itself struck. What God says to those who love Him, they in their degree say to God: "He that toucheth Thee toucheth the apple of mine eye." True, hate is not the Christian requital of hate, whether that is directed against God or God's servant. But recoil there must be, if there is any vigour of devotion; only, pity and love must mingle with it, and the evil of hatred be overcome by their good. Very beautifully does the lowly prayer for searching and guidance follow the psalmist's burst of fire. It is easier to glow with indignation against evil-doers than to keep oneself from doing evil. Many secret sins may hide under a cloak of zeal for the Lord. So the psalmist prays that God would search him, not because he fancies that there is no lurking sin to be burned by the light of God's eye, like vermin that nestle and multiply under stones and shrivel when the sunbeams strike them, but because he dreads that there is, and would fain have it cast out. The psalm began with declaring that Jehovah had searched and known the singer, and it ends with asking for that searching knowledge.
