Kommentar zu Tehillim 17:1

A Prayer of David. Hear right, Lord, attend unto my ringing cry: Give ear to my prayer, that goeth out of no feigned lips. – Hear my prayer, which is (uttered) in righteousness; Hear it for my mouth and heart are at one; and this is the meaning of righteousness, and of no feigned lips. The whole verse is a repetition of the one idea in different terms. רנתי (my ringing cry) also is of the same meaning as צעקתי (my cry), for he who prays sometimes cries with a ringing voice and sometimes in a low tone. Every use of the expression רנה denotes a cry, such being employed sometimes of singing and rejoicing, sometimes of public announcement, sometimes of prayer and entreaty, and sometimes of weeping and groaning; and each (nuance) is distinct, according to its context.
