My heart became hot ... it burned like a fire

Here "heart" represents the whole person. The anxious thoughts of the writer are spoken of as if they were a fire burning inside him. Alternate translation: "I became very anxious when I thought about these things" (See: rc://en/ta/man/jit/figs-synecdoche and rc://en/ta/man/jit/figs-metaphor)
