'Remove' in the Bible

Was anyone at the time of his calling [from God already] circumcised? He is not to become uncircumcised. Has anyone been called while uncircumcised? He is not to be circumcised.

And if I have the gift of prophecy [and speak a new message from God to the people], and understand all mysteries, and [possess] all knowledge; and if I have all [sufficient] faith so that I can remove mountains, but do not have love [reaching out to others], I am nothing.
