What About the Tithe

Malachi 3:

1 ¶ Behold, I will send my messenger, and he shall prepare the way before me: and the Lord, whom ye seek, shall suddenly come to his temple, even the messenger of the covenant, whom ye delight in: behold, he shall come, saith the LORD of hosts.
2 But who may abide the day of his coming? and who shall stand when he appeareth? for he [is] like a refiner’s fire, and like fullers’ soap:
3 And he shall sit [as] a refiner and purifier of silver: and he shall purify the sons of Levi, and purge them as gold and silver, that they may offer unto the LORD an offering in righteousness.
4 Then shall the offering of Judah and Jerusalem be pleasant unto the LORD, as in the days of old, and as in former years.
5 And I will come near to you to judgment; and I will be a swift witness against the sorcerers, and against the adulterers, and against false swearers, and against those that oppress the hireling in [his] wages, the widow, and the fatherless, and that turn aside the stranger [from his right], and fear not me, saith the LORD of hosts.
6 For I [am] the LORD, I change not; therefore ye sons of Jacob are not consumed.
7 ¶ Even from the days of your fathers ye are gone away from mine ordinances, and have not kept [them]. Return unto me, and I will return unto you, saith the LORD of hosts. But ye said, Wherein shall we return?
8 Will a man rob God? Yet ye have robbed me. But ye say, Wherein have we robbed thee? In tithes and offerings.
9 Ye [are] cursed with a curse: for ye have robbed me, [even] this whole nation.
10 Bring ye all the tithes into the storehouse, that there may be meat in mine house, and prove me now herewith, saith the LORD of hosts, if I will not open you the windows of heaven, and pour you out a blessing, that [there shall] not [be room] enough [to receive it].
11 And I will rebuke the devourer for your sakes, and he shall not destroy the fruits of your ground; neither shall your vine cast her fruit before the time in the field, saith the LORD of hosts.
12 And all nations shall call you blessed: for ye shall be a delightsome land, saith the LORD of hosts.

Hebrews 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;
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;
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.
4 Now consider how great this man [was], unto whom even the patriarch Abraham gave the tenth of the spoils.
5 And verily they that are of the sons of Levi, who receive the office of the priesthood, have a commandment to take tithes of the people according to the law, that is, of their brethren, though they come out of the loins of Abraham:
6 But he whose descent is not counted from them received tithes of Abraham, and blessed him that had the promises.
7 And without all contradiction the less is blessed of the better.
8 And here men that die receive tithes; but there he [receiveth them], of whom it is witnessed that he liveth.
9 And as I may so say, Levi also, who receiveth tithes, payed tithes in Abraham.
10 For he was yet in the loins of his father, when Melchisedec met him.
