Psalms 3:2 - Clarke's commentary and critical notes on the Bible

Many there be which say of my soul, There is no help for him in God. Selah. No help for him in God - These were some of the reproaches of his enemies, Shimei and others: "He is now down, and he shall never be able to rise. God alone can save him from these his enemies; but God has visibly east him off." These reproaches deeply affected his heart; and he mentions them with that note which so frequently occurs in the Psalms, and which occurs here for the first time, סלה selah. Much has been said on the meaning of this word; and we have nothing but conjecture to guide us. The Septuagint always translate it by Διαψαλμα diapsalma, "a pause in the Psalm." The Chaldee sometimes translates it by לעלמין lealmin, "for ever." The rest of the versions leave it unnoticed. It either comes from סל sal, to raise or elevate, and may denote a particular elevation in the voices of the performers, which is very observable in the Jewish singing to the present day; or it may come from סלה salah, to strew or spread out, intimating that the subject to which the word is attached should be spread out, meditated on, and attentively considered by the reader. Fenwick, Parkhurst, and Dodd, contend for this meaning; and think "it confirmed by Psalms 9:16, where the word higgaion is put before selah at the end of the verse." Now higgaion certainly signifies meditation, or a fit subject for meditation; and so shows selah to be really a nota bene, attend to or mind this.
