(64-7) They search out iniquities, they have accomplished a diligent search; even in the inward thought of every one, and the deep heart.
King James Version (KJV) - Psalms 64:6 >They search out iniquities; they accomplish a diligent search: both the inward [thought] of every one [of them], and the heart, [is] deep.
Berean Study Bible (BSB) - Psalms 64:6 >They devise injustice and say, “We have perfected a secret plan.” For the inner man and the heart are mysterious.
