Psalms 17:3-5

³Thou hast proved my heart; thou hast thought of me in the night; thou hast refined me—thou couldst find nothing: my purpose doth not pass beyond the words of my mouth.

⁴Among the deeds of men did I observe, by the word of thy lips, the paths of the dissolute.

⁵My steps held firmly to thy tracks, and my footsteps did not slip.
