Only be strong and very courageous, that you may observe to do according to all the law which Moses My servant commanded you; do not turn from it to the right hand or to the left, that you may prosper wherever you go. This Book of the Law shall not depart from your mouth, but you shall meditate in it day and night, that you may observe to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success. Have I not commanded you? Be strong and of good courage; do not be afraid, nor be dismayed, for the Lord your God is with you wherever you go.” (Joshua 1:7-9)
I would have lost heart, unless I had believed
That I would see the goodness of the Lord
In the land of the living.
Wait on the Lord;
Be of good courage,
And He shall strengthen your heart;
Wait, I say, on the Lord! (Psalm 27:13-14)
