You have a raven's knowledge.
Without knowledge, without sin.
Who teaches another, acquires more knowledge.
There are three "too much" and three "too little" that can bring a fool down: too much spending and too little money; too much talking and too little knowledge; and too much boasting and too little earnings.
The wise man who does not put his knowledge into practice is like a bee that gives no honey.
The wise man does not hang his knowledge on a hook.
The old for want of ability, and the young for want of knowledge, let things be lost.
The man of sense does not hang up his knowledge.
The knowledge of sin is the beginning of salvation.
