Tafsiran Mazmur 5:3: Radak

Hearken unto the voice of my cry: – Make thine ear attentive, for the verb (הקשׁיבה) is transitive. And so it is written (Prov. 2:2): “to incline (להקשׁיב) thine ear unto wisdom”; “Thou wilt make attentive thine ear” (Ps. 10:17). The word is connected with (the prepositions) ל, אל, and ב; and sometimes it is (used) without any connecting letter (at all), as ואשׁמע הקשבתי, “I hearkened and heard” (Jer. 8:6); מי הקשׁיב דברו, “Who hath hearkened to his word?” (ibid, 23:17).

my King: – for Thou art a king over me, and I cry unto Thee as men cry unto the king.

and my God (Judge) – art Thou, for Thou art my Judge and shalt save me from those who do me evil.
