he walked firmly before Yahweh his God

Jotham's actions and lifestyle are spoken of as if they were a path upon which he walked. That he walked firmly means that he was devoted to living in this way. Alternate translation: "he faithfully obeyed Yahweh his God" (See: rc://en/ta/man/translate/figs-metaphor)
