(Some words not found in UHB: and,they,will_stone_him all/each/any/every men_of his_city_of,his with,stones and,he_will_die and,you_will_remove the,evil from,midst_of,your and=all Yisrael they_will_understand and,they_will_fear )

See how you translated this same phrase in 13:5.

Note 2 topic: grammar-connect-logic-result

וְ⁠כָל־יִשְׂרָאֵ֖ל יִשְׁמְע֥וּ וְ⁠יִרָֽאוּ

and=all (Some words not found in UHB: and,they,will_stone_him all/each/any/every men_of his_city_of,his with,stones and,he_will_die and,you_will_remove the,evil from,midst_of,your and=all Yisrael they_will_understand and,they_will_fear )

The words And all Israel will hear and fear indicate the result of executing the rebellious son. If it would be clearer in your language, you could make this logical relationship explicit. Alternate translation: [As a result, all Israel will hear about this punishment and be afraid to behave in the same way]
