Okay, I'm in on this! Here are two my favorite verses:

Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee. -Isaiah 26:3

No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn. This is the heritage of the servants of the Lord, and their righteousness is of me, saith the Lord.
-Isaiah 54:17
