'Good Courage' in the Bible

and what manner of land it is, whether it be fat or lean, and whether there be trees therein or not. And be of a good courage, and bring of the fruits of the land." And it was about the time that grapes are first ripe.

And whosoever disobey thy mouth, and will not hearken unto thy words in all that thou commandest him, let him die: Only be strong and of good courage."

But David took a good courage to him in the LORD his God and said to Abiathar the priest, Ahimelech's son, "Bring me the ephod." And Abiathar brought the ephod to David.

Sing unto the LORD a new song; sing praises lustily unto him, and with a good courage.
