'Furthermore' in the Bible

Furthermore, when I came to Troas to preach Christ's gospel, and a door was opened unto me of the Lord,

Furthermore then we beseech you, brethren, and exhort you by the Lord Jesus, that as ye have received of us how ye ought to walk and to please God, so ye would abound more and more.

Furthermore we have had fathers of our flesh which corrected us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live?
