'Clear' in the Bible

And they were all filled [that is, diffused throughout their being] with the Holy Spirit and began to speak in other tongues (different languages), as the Spirit was giving them the ability to speak out [clearly and appropriately].

for I will make clear to him how much he must suffer and endure for My name’s sake.”

In view of this, I also do my best and strive always to have a clear conscience before God and before men.
