Charles H. Spurgeon on Psalms 142:1

With my voice. The Lord needs not the tongue to be an interpreter between him and the hearts of his children. He that hears without ears can interpret prayers though not uttered by the tongue. Our desires are cries in the ears of the Lord of hosts. The vehemency of the affections may sometimes cause the outcrying of the voice; but alas! Without this it is but a tinkling cymbal...There is a use of words in prayer, to excite, and convey, and give vent to, affection: Ho 14:2, "Take with you words, and turn to the Lord: say unto him, Take away all iniquity, and receive us graciously." The prophet doth not only prescribe that they should take affections, but take with them words. —Thomas Manton.
