Psalm 15:1-5 DSS reference

I originally posted this question under the Biblical Hermeneutics Stack Exchange site, but I noticed a number of references to the Dead Sea Scrolls in this community so I thought I'd try my luck here. In reading Robert Alter's book on the Psalms, he mentioned a missing (DSS) verset in Psalm 15 (𝜳15:3 — ". . who slanders not with his tongue."). I found a DSS link to these verses in a work by Leon Levy, Dead Sea Scrolls digital library. The specification for these missing words is: Manuscript - 5/6HevPs; Location - 5/6Hev 1b. In trying to find the Plate/Fragment# containing Ps. 15:1-5, I haven't had much success and was hoping someone in this community has traversed this terrain before me and can point me in the right direction. Interestingly, the LXX does have this reference to slandering with the tongue, which introduces a whole other topic/thread regarding the relationship between the Septuagint and the Masoretic text. However, currently that's not my interest as much as the original(?) Hebrew text. Any help would be much appreciated. Thanks!
