(
Heb 7:1) For this Melchisedec, king of Salem, priest of the most high God, who met Abraham returning from the slaughter of the kings, and blessed him;
(
Heb 7:2) To whom also Abraham gave a tenth part of all; first being by interpretation King of righteousness, and after that also King of Salem, which is, King of peace;
(
Heb 7:3) Without father, without mother, without descent, having neither beginning of days, nor end of life; but made like unto the Son of God; abideth a priest continually.
(
Heb 7:4) Now consider how great this man was, unto whom even the patriarch Abraham
gave the tenth of the spoils.
(
Mat 23:23) Woe unto you, scribes and Pharisees, hypocrites! for
ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: these ought ye to have done,
and not to leave the other undone.
Tithing didn't start under the law, it started in Genesis.
If you are Abraham's seed you will also pay tithes just like he did!
