ציטירנדיקער פּירוש אויף תהילים 5:9

upon those who stare at me Heb. בשורי, at those who stare at me, as (5:9): “those who lie in wait for me (בשוררי).”

after their heart’s fantasies Heb. בשרירותלבם, after the views of their heart, as (above 5: 9): “because of those who lie in wait for me (שוררי).”

הוצא, the letter ו in the middle instead of the letter י is not unusual in verbs whose first root letter is supplanted by the letter ו. Nonetheless the ו is read as if it were a י. We have a similar construction in Psalms 5,9 הישר לפני דרכך, which is spelled הושר, “make Your way straight before me.” Proverbs 4,25 יישירו נגדך is another such example. The meaning of the instruction is: “take them out just as you have brought them in!”

they lie in wait Heb. ישור. Comp. למען שוררי because of those who lie in wait for me (Psalms 27: 11), an expression of “I see him (אשורנו) but not near” (Num. 24:17).
