For this is he, of whom it is written, Behold, I send my messenger before thy face, which shall prepare thy way before thee.
Matthew 3:3
for this is he who was spoken of by Isaiah the prophet, saying, 'A voice of one crying in the wilderness, Prepare ye the way of the Lord, straight make ye His paths.'
Lo, I am sending My messenger, And he hath prepared a way before Me, And suddenly come in unto his temple Doth the Lord whom ye are seeking, Even the messenger of the covenant, Whom ye are desiring, Lo, he is coming, said Jehovah of Hosts.
