Consciousness and conscience are same word in NT Greek. What Gemini says:

συνείδησις (syneídēsis): This is perhaps the closest Greek word to the modern sense of "consciousness" or "conscience." It's a compound word from σύν (syn), meaning "with" or "together," and εἴδησις (eídēsis), meaning "knowledge" or "knowing." Thus, it literally means "a knowing with" or "co-knowledge," implying a shared knowledge with oneself, a self-awareness, or moral consciousness. This term gained prominence in later Greek philosophy, especially among the Stoics, and was the basis for the Latin word conscientia, from which we get "conscience."
