And he said, “O man greatly loved, fear not, peace be with you; be strong and of good courage.” And as he spoke to me, I was strengthened and said, “Let my lord speak, for you have strengthened me.”
Joshua 1:9 (NIV)
Have I not commanded you? Be strong and courageous. Do not be terrified; do not be discouraged, for the Lord your God will be with you wherever you go.”
