We look at the first 2 verses of Wesley's Carol:

Let earth and Heaven combine,
Angels and men agree,
To praise in songs divine
The incarnate Deity,
Our God contracted to a span,
Incomprehensibly made man.

He laid His glory by,
He wrapped Him in our clay;
Unmarked by human eye,
The latent Godhead lay;
Infant of days He here became,
And bore the mild Immanuel’s name.
