Various taxes appear to have operated in Israel, but the most significant and divinely ordained general tax was probably the tithe (a tax of 10%). This was essentially a flat rate form of income tax (Lev 27:30-33; Dt 14:22ff).
In Solomon�s time, despite huge revenues from trade, the royal palace needed further revenues. A system of taxation was set up which included the areas controlled by the various Northern tribes, but not Judah and Benjamin (1 Ki 4:7-19). Jerusalem was located in Judah who thus escaped paying taxes for the activities of the palace, of which they would be the most direct beneficiaries. This differential treatment reflected the tribal divisions that David had faced (2 Sam 3:1; 5:1-3; etc.).
On Solomon�s death, his son offered the Northern tribes no relief and they rebelled. The kingdom was divided from that time, the Bible dating the rebellion from the stoning of the king�s tax collector (1 Ki 12: 18-19; 2 Ch 10:18-19). Thus, funding the government of the nation instead divided and destroyed it. Unfair taxes were also levied at other times (e.g. the grain tax in Amos 5:11).
There are repeated warnings against providing security (a surety or pledge) for others� debts (Pr 6:1; 11:15; 17:18; 22:26). Where a government has debts, the basic security is the public assets it owns and its future ability to raise taxes. The taxpayer, or future taxpayers, are providing security, but without being consulted: �For the children ought not to lay up for the parents, but the parents for the children� (2 Cor 12:14).
Money is a measure and store of value. Inflation may be said to run counter to Biblical injunctions against moving landmarks (Dt 19:14; Pr 22:28) and requiring the use of fair weights, scales and measures (Dt 25:13-16; Lev 19:36- 36; Pr 20:23).
This is reinforced by the way government can benefit from inflation. Without legislation or
consultation, it can reduce the real (that is, after adjusting for inflation) value of its debts and increase its effective
tax rates. Inflation operates against those least able to adjust for its impact. It can be seen as a form of robbery (just
as debasing the coinage was in Biblical times): �Your silver has become dross...Your princes are rebellious, And
companions of thieves� (Is 1:22-23).
* Unfair taxes may reflect and exacerbate social divisions and divide nations. Simple and universal taxes are
preferable.
* Public debt is to be minimised.
* Inflation is to be minimised.
