출애굽기 23:7의 Musar

But the wisest of men (Shlomo) has taught us that all of this is contrary to the will of the Creator, blessed be He, and the attributes of His pious ones as written: "the righteous man hates a false word" (Mishlei 13:5). This is also what the Torah commands us: "keep far from a false matter" (Shemot 23:7). Notice that the verse did not say "guard against falsehood" but rather "keep far from a false matter", to rouse us on the great extent one must distance and flee far away from falsehood, as scripture says: "The remnant of Israel shall not do iniquity nor speak lies, and a deceitful tongue shall not be found in their mouths" (Tzefania 3:13).

As for him who speaks the truth, there is no quality like it. Therefore, "The beginning of thy word is truth" (Ps. 119:160). And it is said, "Keep thee far from a false matter" (Ex. 23:7).
