Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the Lord:
And he shall turn the heart of the fathers to the children, and the heart of the children to their fathers, lest I come and smite the earth with a curse.(Malachi 4:5-6)
And it shall come to pass in the last days, that the mountain of the Lord’s house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it.
And many people shall go and say, Come ye, and let us go up to the mountain of the Lord, to the chouse of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the Lord from Jerusalem.(Isaiah 2:2-3)
