As a rule לֹא stands immediately before the verb, but sometimes is separated from it (frequently to bring into special prominence another word which follows it); thus Jb 22:7, Ec 10:10 before the object and verb; Nu 16:29 before the subject and verb; Dt 8:9, 2 S 3:34, y Ps 49:18, 103:10, Jb 13:16, 34:23 before a complementary adjunct.
