Proverbs 8:8 New English Translation

⁸All the words of my mouth are righteous;^[a]
there is nothing in them twisted^[b] or crooked.

Proverbs 8:8 tn The phrase could be rendered with an understood ellipsis: “all the words of my mouth [are said] in righteousness”; or the preposition could be interpreted as a beth essentiae: “all the words of my mouth are righteousness.”
Proverbs 8:8 sn The verb פָּתַל (patal) means “to twist.” In the Niphal it means “to wrestle” (to twist oneself). It was used in Gen 30:8 for the naming of Naphtali, with the motivation for the name from this verb: “with great struggling.” Here it describes speech that is twisted. It is a synonym for the next word, which means “twisted; crooked; perverse.”
