And it shall be said in that day, Lo, this is our God; we have waited for him, and he will save us: this is the LORD; we have waited for him, we will be glad and rejoice in his salvation.

Lo, thou trustest in the staff of this broken reed, on Egypt; whereon if a man lean, it will go into his hand, and pierce it: so is Pharaoh king of Egypt to all that trust in him.

Behold, these shall come from far: and, lo, these from the north and from the west; and these from the land of Sinim.

Behold, the Lord GOD will help me; who is he that shall condemn me? lo, they all shall wax old as a garment; the moth shall eat them up.
