Psalms 143:2

But when I appeal to thy righteousness, I do it only with respect to mine enemies, whose cause as well as their persons is worse than mine, but not in reference to thee, as if I could absolutely justify myself upon a severe trial at the tribunal of thy justice; for if thou shouldst rigorously examine all the passages of my heart and life, I dread the thoughts and consequences of it. Be justified, to wit, upon terms of strict justice, without thy indulgence and infinite mercy.
