-Proverbs 18:10

He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty. I will say of the Lord, He is my refuge and my fortress: my God; in him will I trust. Surely he shall deliver thee from the snare of the fowler, and from the noisome pestilence. ...
-Psalm 91

A little one shall become a thousand, and a small one a strong nation: I the Lord will hasten it in his time.
