How The Ten Commandments Are Grouped

(2) Augustine supposed that there were three commandments on the first table and seven on the second. According to his method of numbering the commandments, this would put the command to honor parents at the head of the second table, as in the third method of grouping the ten words.
(3) Calvin and many moderns assign four commandments to the first table and six to the second. This has the advantage of assigning all duties to God to the first table and all duties to men to the second. It also accords with our Lord's reduction of the commandments to two (Mat 22:34-40).
