'Knowledge' in the Bible

For the prophets who gave the news of the grace which would come to you, made search with all care for knowledge of this salvation;

Like children ruled by God, do not go back to the old desires of the time when you were without knowledge:

Likewise, ye husbands, dwell with them according to knowledge, giving honour unto the wife, as unto the weaker vessel, and as being heirs together of the grace of life; that your prayers be not hindered.

Do not give way to him but be strong in your faith, in the knowledge that your brothers who are in the world undergo the same troubles.
