וַ֭אֲנִי בְּתֻמִּ֥י אֵלֵ֗ךְ פְּדֵ֣נִי וְחָנֵּֽנִי׃
나는 나의 완전함에 행하오리니 나를 구속하시고 긍휼히 여기소서

He that walketh perfectly: – If תמים (perfect) is an adjective, his meaning is, One who walks in a perfect way, as, “He that walketh in a perfect way, he shall minister unto me” (ibid. 101:6); while if it is a noun, (it is used) as (in the passage) “if in truth and perfectness (בתמים)” (Judges 9:16). He means: He who walks in perfectness (integrity), as, “But as for me I will walk in mine integrity (בתמי)” (Ps. 26:11). But in either case the meaning is the same. The perfect is he who occupies himself in the affairs of this world in the way of perfectness (integrity), who does not engage his deepest purpose in (the prosecution of) worldly schemes.
