'Comes' in the Bible

"Behold, I send my messenger, and he will prepare the way before me; and the Lord, whom you seek, will suddenly come to his temple; and the messenger of the covenant, whom you desire, behold, he comes!" says Yahweh of Armies.

But who will survive the day when he comes? Or who can stand when he appears? Because he's like a refiner's fire and a launderer's soap,

“For behold, the day is coming, burning like a furnace, and all the arrogant (proud, self-righteous, haughty), and every evildoer shall be stubble; and the day that is coming shall set them on fire,” says the Lord of hosts, “so that it will leave them neither root nor branch.

Look, I am going to send you Elijah the prophet before the great and awesome Day of the Lord comes.
