'Full' in the Bible

But strong meat belongeth to them that are of full age, even those who by reason of use have their senses exercised to discern both good and evil.

And we desire that every one of you do shew the same diligence to the full assurance of hope unto the end:

Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water.
