uW Translation Notes:

Note 1 topic: translate-textvariants

וַ⁠יִּשְׁמַ֣ע עֲלֵי⁠הֶם֮ חִזְקִיָּהוּ֒

(Some words not found in UHB: and=he/it_listened to,them Ḩizqiy^yāh and,he,showed_them DOM all/each/any/every house_of his_treasure_of,his DOM the,silver and=DOM the=gold and=DOM the,spices and=DOM oil_of (the),good and=DOM house_of his_weapons_of,his and=DOM all/each/any/every which/who he/it_was_found in,storehouses_of,his not it_became thing which/who not he,showed_them Ḩizqiy^yāh in,house_of,his and=on/over=all realm_of,his )

Some ancient manuscripts read “And Hezekiah listened to them.” The ULT follows that reading. Other ancient manuscripts and the parallel passage in Isaiah 39:2 read “And Hezekiah rejoiced over them.” If a translation of the Bible exists in your region, you may wish to use the reading that it uses. If a translation of the Bible does not exist in your region, you may wish to use the reading of the ULT.

Note 2 topic: figures-of-speech / idiom

וְ⁠אֵ֛ת כָּל־אֲשֶׁ֥ר נִמְצָ֖א בְּ⁠אֽוֹצְרֹתָ֑י⁠ו

and=DOM (Some words not found in UHB: and=he/it_listened to,them Ḩizqiy^yāh and,he,showed_them DOM all/each/any/every house_of his_treasure_of,his DOM the,silver and=DOM the=gold and=DOM the,spices and=DOM oil_of (the),good and=DOM house_of his_weapons_of,his and=DOM all/each/any/every which/who he/it_was_found in,storehouses_of,his not it_became thing which/who not he,showed_them Ḩizqiy^yāh in,house_of,his and=on/over=all realm_of,his )

See how you translated the similar expression in 12:18. Alternate translation: [and everything that was in his treasuries]

Note 3 topic: figures-of-speech / doublenegatives

לֹֽא־הָיָ֣ה דָבָ֗ר אֲ֠שֶׁר לֹֽא־הֶרְאָ֧⁠ם חִזְקִיָּ֛הוּ בְּ⁠בֵית֖⁠וֹ וּ⁠בְ⁠כָל־מֶמְשַׁלְתּֽ⁠וֹ

not it_became thing not (Some words not found in UHB: and=he/it_listened to,them Ḩizqiy^yāh and,he,showed_them DOM all/each/any/every house_of his_treasure_of,his DOM the,silver and=DOM the=gold and=DOM the,spices and=DOM oil_of (the),good and=DOM house_of his_weapons_of,his and=DOM all/each/any/every which/who he/it_was_found in,storehouses_of,his not it_became thing which/who not he,showed_them Ḩizqiy^yāh in,house_of,his and=on/over=all realm_of,his )

This is a double negative, consisting of two instances of the negative particle not. If it would be clearer in your language, you could use a positive expression to translate this. Alternate translation: [Hezekiah showed them everything in his palace and in his realm]
