Charles H. Spurgeon on Psalms 142:1

I cried unto the LORD with my voice. It was a cry of such anguish that he remembers it long after, and makes a record of it. In the loneliness of the cave he could use his voice as much as he pleased; and therefore he made its gloomy vaults echo with his appeals to heaven. When there was no soul in the cavern seeking his blood, David with all his soul was engaged in seeking his God. He felt it a relief to his heart to use his voice in his pleadings with Jehovah. There was a voice in his prayer when he used his voice for prayer: it was not vox et praeterea nihil. It was a prayer vivo corde as well as vivâ voce. With my voice unto the Lord did I make my supplication. He dwells upon the fact that he spoke aloud in prayer; it was evidently well impressed upon his memory, hence he doubles the word and says, "with my voice; with my voice." It is well when our supplications are such that we find pleasure in looking back upon them. He that is cheered by the memory of his prayers will pray again. See how the good man's appeal was to Jehovah only: he did not go round about to men, but he ran straight forward to Jehovah, his God. What true wisdom is here! Consider how the Psalmist's prayer grew into shape as he proceeded with it. Its first poured out his natural longings, —"I cried"; and then he gathered up all his wits and arranged his thoughts, —"I made supplication." True prayers may differ in their diction, but not in their direction: an impromptu cry and a preconceived supplication must alike ascend towards the one prayer hearing God, and he will accept each of them with equal readiness. The intense personality of the prayer is noteworthy: no doubt the Psalmist was glad of the prayers of others, but he was not content to be silent himself. See how everything is in the first person, —"I cried with my voice; with my voice did I make my supplication." It is good to pray in the plural —"Our Father", but in times of trouble we shall feel forced to change our note into "Let this cup pass from me."
