Hear, O Lord, when I cry with my voice,.... Which is to be understood of prayer, and that in the time of distress; and of vocal prayer, as distinguished from mental prayer; and the phrase denotes the vehemency and intenseness of it: and the request is, that the Lord would hear it; not only as he is omniscient and omnipresent, and so hears the prayers of all, good and bad; but as a God gracious and merciful, who sometimes very quickly hears, and answers in a gracious way, and sometimes seems to turn a deaf car, to shut out the prayers of his people, and cover himself with a cloud, that they should not pass through, or, however, defers an answer to it for a little while; yet, sooner or later, he always shows himself a God hearing prayer; have mercy also upon me; by delivering him out of his temporal distresses, and by forgiving his iniquities; and answer me; by speaking a word in season; commanding off the affliction he lay under, and by saying to him that his sins were forgiven him.
