KENA UPANISHAD 4:8 {stands knowledge}

Before the tempering of passion, the restraint of sensibilities, and the totality of action ultimately stands knowledge, in which all branches of truth are supported.

tasmai tapo damah karmeti pratishtha vedah sarvangani satyam ayatanam.

Notes: The key word appears to be ‘tasmai’ indicating in front or before. And the key relationships appear to be the previous appearances of fire, air, and sky in association with tapo, damah, and karmeti, indicating the tempering of passion (fire), the restraint of sensibilities (air), and the totality (sky) of action.
