'Furthermore' in the Bible

Furthermore, here [in the Levitical priesthood] tithes are received by men who are subject to death; but in that case [concerning Melchizedek], they are received by one of whom it is testified that he lives on [perpetually].

Furthermore, it is obvious that our Lord was a descendant of Judah, and Moses said nothing about priests coming from that tribe.

Every priest stands [at his altar of service] ministering daily, offering the same sacrifices over and over, which are never able to strip away sins [that envelop and cover us];

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?
