'Eloquence' in the Bible

So Moses was educated in all the learning of the Egyptians, and possessed great influence through his eloquence and his achievements.

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.

For they say "His letters are authoritative and forcible, but his personal presence is unimpressive, and as for eloquence, he has none."
