Matthew 16:18-20

Young's Literal Translation

¹⁸ `And I also say to thee, that thou art a rock, and upon this rock I will build my assembly, and gates of Hades shall not prevail against it;

¹⁹ and I will give to thee the keys of the reign of the heavens, and whatever thou mayest bind upon the earth shall be having been bound in the heavens, and whatever thou mayest loose upon the earth shall be having been loosed in the heavens.'

²⁰ Then did he charge his disciples that they may say to no one that he is Jesus the Christ.
