Charles H. Spurgeon on Psalms 59:13

That they may not be. By the word wmgyaw, that they may not be, may be understood either a vile and wretched state in general, or even total destruction. The former must indeed here be admitted, as is plain from the context, yet not to the exclusion of the latter sense; since a miserable condition, such as in a disease, issues in destruction at length. Not to be is evidently by no means rarely taken for to be nobody, to be wretched, afflicted, despised. Compare Jer 31:15. Hermann Venema.
