Matthew Poole and continuators on Psalms 142:1

1 I Cried unto the LORD with my voice : with my voice unto the LORD did I make my supplication.

Either, 1. with the voice of my soul. But so this addition would be superfluous, and much more the repetition of it, because that is necessarily implied in the former word, I cried, and in the following, I make my supplication. Or rather, 2. with my corporeal voice, which the fervor of my soul forced me to use, when I could not do it without some danger, the enemy being at the mouth of the cave. And so this addition is emphatical, and therefore is repeated. But it is probable that David spoke with a low voice, and that he might do so without very great danger, is manifest from that discourse which passed between David and his men, even when Saul was entred into the cave, 1 Sam. 24, 4, 5, 6, 7.
