There is also a belief that every third year a special or additional tithe was to be collected.
When you have finished setting aside a tenth of all your produce in the third year, the year of the tithe, you shall give it to the Levite, the foreigner, the fatherless and the widow, so that they may eat in your towns and be satisfied. (Deut. 26:12 NIV)
Some have supposed this to be the third and sixth year out of a seven year cycle.
Additionally there are indications that perhaps another tithe was to be used to attend religious festivals.
Deut 12:17 and Deut 14:23.
But the main point that MAY connect with what you are writing is that the cycles of seven MIGHT be the framework from which the three year cycle (if it is counted within the seven year cycle) is derived. Otherwise there is a whole other series of cycles to add to the cycles you are already looking at Ron.
