tah.pu.khah denotes corrupt or twisted speech, intentions, and conduct set against wisdom, faithfulness, and what is acceptable.

The term consistently marks corruptness expressed in speech, inward planning, and harmful conduct: mouths and hearts produce it, people devise or delight in it, and it characterizes a generation lacking faithfulness.

   The plural noun identifies what wicked mouths speak in Proverbs 10:32 and Proverbs 23:33, and it describes the speech of the man from whom wisdom delivers in Proverbs 2:12. It also concerns inward and active wrongdoing: in Proverbs 6:14 the APB renders it as being "in his heart" while he plots evil and stirs strife, and in Proverbs 16:30 it is what a person devises before finishing harm. Deuteronomy 32:20 applies the same plural form to a generation described as having no faithfulness.
