The peten — deaf to the charmer in Tehillim 58, safe beside the weaned child in Yeshayahu 11. Traditionally the cobra or asp; the identification is discussed.
חֲמַת תַּנִּינִם יֵינָם וְרֹאשׁ פְּתָנִים אַכְזָֽר
Their wine is the venom of serpents, And the cruel poison of asps.
וְשִֽׁעֲשַׁע יוֹנֵק עַל־חֻר פָּתֶן וְעַל מְאוּרַת צִפְעוֹנִי גָּמוּל יָדוֹ הָדָֽה
And the sucking child shall play on the hole of the asp, And the weaned child shall put his hand on the basilisk’s den.
חֲמַת־לָמוֹ כִּדְמוּת חֲמַת־נָחָשׁ כְּמוֹ־פֶתֶן חֵרֵשׁ יַאְטֵם אָזְנֽוֹ
Their venom is like the venom of a serpent; They are like the deaf asp that stoppeth her ear;
עַל־שַׁחַל וָפֶתֶן תִּדְרֹךְ תִּרְמֹס כְּפִיר וְתַנִּֽין
Thou shalt tread upon the lion and asp; The young lion and the serpent shalt thou trample under feet.
לַחְמוֹ בְּמֵעָיו נֶהְפָּךְ מְרוֹרַת פְּתָנִים בְּקִרְבּֽוֹ
Yet his food in his bowels is turned, It is the gall of asps within him.
רֹאשׁ־פְּתָנִים יִינָק תַּֽהַרְגֵהוּ לְשׁוֹן אֶפְעֶֽה
He shall suck the poison of asps; The viper’s tongue shall slay him.
