John Calvin Commentary Psalms 119:170

"Let my supplication come before thee: Deliver me according to thy word." — Psalms 119:170 (ASV)

Let my prayer come into your presence. After making supplication that the gift of right understanding might be given to him, the Psalmist now implores God for deliverance. By this, he acknowledges that he was continually involved in multiplied dangers from which he found it impossible to escape, unless God stretched out His hand from heaven to help him.

We know, indeed, that whenever any distress was pressing hard behind him, he called upon God for help. But since he does not specify any particular distress here, I have no doubt that, in commending his life in general terms to God's protection, he thought again and again how he was hemmed in on every side by innumerable deaths, from which he could not escape if God did not prove to be his continual deliverer.

But this is an inestimable comfort to us: that God assures us that in all dangers He will be ready and prepared to help us.
