A prudent man concealeth knowledge.
Concealing knowledge
I. When it is opportune (John 16:12).
II. When it is above the capacity of his hearers (1 Corinthians 2:2).
III. When likely to be misapplied (Mark 15:5).
IV. When sure of rejection (Matthew 7:6).
V. When calculated to injure the brethren (Leviticus 19:16).
VI. When to utter it would be only for self-display (Proverbs 27:2). (R. A. Griffin.)
