Myśl Żydowska do Psalmów 101:2

You should realize that the aim and value of the duties of the heart is that our exterior and interior be equal and consistent in the service of G-d, so that the testimony of the heart, tongue, and limbs be alike, and that they support and confirm each other instead of differing and contradicting each other. This is what Scripture calls "tamim" (innocent/perfect), in saying: "You shall be perfect with the L-ord your G-d" (Deut. 18:13), and "Noah was a righteous man and perfect in his generations" (Gen. 6:9), and "he who walks uprightly, and works righteousness, and speaks the truth in his heart" (Ps. 15:2), and "I will give heed unto the way of integrity..I will walk within my house with a perfect heart" (Ps. 101:2).
