'Earthly' in the Bible

And as for myself, brethren, when I came to you, it was not with surpassing power of eloquence or earthly wisdom that I came, announcing to you that which God had commanded me to bear witness to.

And my language and the Message that I proclaimed were not adorned with persuasive words of earthly wisdom, but depended upon truths which the Spirit taught and mightily carried home;

There are bodies which are celestial and there are bodies which are earthly, but the glory of the celestial ones is one thing, and that of the earthly ones is another.
