'Plainly' in the Bible

[and besides this evidence] God also testifying with them [confirming the message of salvation], both by signs and wonders and by various miracles [carried out by Jesus and the apostles] and by [granting to believers the] gifts of the Holy Spirit according to His own will.

And this becomes even more evident if another priest arises in the likeness of Melchizedek,

For they that say such things declare plainly that they seek a country.
