וְ⁠נָתֹ֥ן אֶת־אֱלֹהֵי⁠הֶ֖ם בָּ⁠אֵ֑שׁ כִּי֩ לֹ֨א אֱלֹהִ֜ים הֵ֗מָּה כִּ֣י אִם־מַעֲשֵׂ֧ה יְדֵֽי־אָדָ֛ם עֵ֥ץ וָ⁠אֶ֖בֶן וַֽ⁠יְאַבְּדֽוּ⁠ם

If it would be more natural in your language, you could reverse the order of these phrases, since the second phrase gives the reason for the result that the first phrase describes. Alternate translation: [And since their gods are not gods, but rather the work of the hands of man, wood and stone, they have put them in the fire and destroyed them]

Hezekiah is using one part of people, their hands, to mean all of them in the act of making gods out of wood and stone. If it would be helpful in your language, you could state the meaning plainly. Alternate translation: [the work of craftsmen]
