Biblical narrative

According to Biblical text, the commandments represent the covenants agreed to on Mt. Horab. The description of the tablets in the story says they were carved in stone housed in an ark, and the ark placed in a sanctuary in the Egyptian manner. This creation of a written mosaic law and the idea that it should be held sacred and sovereign over all the commandments of other gods lead to the idea of an inflexible law carved in stone but this was later modified by the selection of judges who could interpret any ambiguities.
There are biblical passages that also refer to ten commandments being written by God on stone, and it is widely though not universally held that these were the Ten Commandments as detailed (see also: "Ritual Decalogue" for an alternative view). The commandments were inscribed on what is called "tablets of stone", also referred to as "tablets of testimony"or "tablets of the Covenant,that God gave to Moses. Moses then gave them to the people of Israel in the third month after their Exodus from Egypt. Israel's receipt of the commandments occurred on the third day of preparations at the foot of the mount
Advocates of this Reformed view hold that, while not always easy to do and overlap between categories does occur, the divisions they make are possible and supported based on information contained in the commands themselves; specifically to whom they are addressed, whom or what they speak about, and their content. For example, a ceremonial law might be addressed to the Levites, speak of purification or holiness and have content which could be considered as a foreshadowing of some aspect of Christ's life or ministry.
In keeping with this, most advocates also hold that when the Law is spoken of as everlasting, it is in reference to certain divisions of the Law. Some advocates, usually Theonomists, go further and embrace that idea that the whole Law continues to function, contending that the way in which Christians observe some commands has changed but not the content or meaning of the commands. (For example, they would say that the commands regarding Passover were looking forward to Christ's sacrificial death and the Communion mandate is looking back on it, the former is given to the Levitical priesthood and the latter is given to the priesthood of all believers, but both have the same content .
