Psalms 77:3

3. I remembered God, and was troubled Or, moaned. This remembrance of God corresponds to his seeking him in the previous verse, and the trouble, or moaning, to the stretching out of his hand, specimens of poetic parallelism. He was “troubled” because God was now withdrawn and hidden from him.

I complained Hebrew, meditated, same word as is rendered “commune,” Psalms 77:6. To meditate is to hold a subject steadily before the mind, to consider it in all its relations; more intensive than remember; thus, “I remembered God and was troubled; I meditated and was overwhelmed.”
