I cried unto the Lord with my voice - See the notes at Psalms 3:4, where the language is the same. He uttered a loud and audible prayer, though he was alone. It was not a mental ejaculation, but he gave expression to his desires.
With my voice unto the Lord did I make my supplication - See Psalms 30:8. The Hebrew word rendered “did make my supplication,” means to implore favor or mercy. It denotes the language of petition and entreaty, not the language of claim.
