I’m going to be as brief as I can.
The only people in the entire bible who were ever directed to tithe, were the Israelites under the old covenant, (prior to the cross). There is no biblical directive for any Christian to either receive tithes, or to pay tithes. It became obsolete when the Levitical priesthood became obsolete, (when the new covenant replaced the old covenant), at the death of Christ.
1. The tithe was never money, (even when money existed). It was an agricultural offering to God, and was the support apparatus for the Levitical priests, (who had no means to provide for themselves).
2. Abram’s tithe to Melchizedek in Genesis 14.18-20 predated the law, but it was never meant to be a tithing directive. For one thing, Abram tithed once, (with assets that weren’t his). But more telling, is this fact: Abram tithed from the spoils of war that he and his war party possessed in their rescue of his nephew Lot. Only Abram tithed out of all of the men of his group. If this were meant to be a tithing directive for today, then only the leader of a group would tithe, while everyone else in the group will not tithe. In other words, if Abram’s tithe was meant to be a tithing directive in general, then everyone in Abram’s group would have tithed.
Here’s the real reason for Abram’s tithe, (found in Hebrews 7). Abram’s tithe was a show of subordination to a representation of Christ. (Because in future generations), the dyed-in-the-wool Jew had to see that Abraham, (or being a biological descendant from Abraham), wasn’t where their faith should rest. Their faith should rest on Him who is above Abraham…the Lord Jesus Christ.
Here’s your new covenant giving directive,
“Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.” 2 Corinthians 9.7
“Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage.” Galatians 5.1
