In my distress I called upon the LORD, and cried unto my God: he heard my voice out of his temple, and my cry came before him, even into his ears.
In my distress I called upon the Lord, and cried unto my God - "I cried" implies a sense of more imminent danger, than "I called." "My God." implies not the mere cry of nature, such as even the ungodly utter in pain, but the cry of filial confidence to God as HIS Father.
He heard my voice out of his temple - i:e., out of heaven. His exaltation there does not lift Him above the reach of our cry, but enables Him the more effectually to 'come down' for our relief (cf. Psalms 18:9).
