“‘See!

I am sending

My messenger

To prepare the way

Before me.

Yahweh,

Whom you seek,

Will suddenly come

To his temple.

The messenger of the covenant,

In whom you delight,

Indeed,

He is coming.’

Says Yahweh of hosts.”

The Gospel of Matthew, chapter 11, applied this text along with Isaiah, chapter 40, to John the Baptist.  Just as Yahweh was sending his messenger to prepare his way, so too John the Baptist would prepare the way for Jesus the Christ.  Yahweh was sending his messenger to prepare his way for his re-entrance into his Temple.  Yahweh would suddenly come, because the messenger of the delightful covenant had prepared things for him.
