Definition: "Fi2" comes from a Latin root meaning "to speak." It's used in the Bible for the phrase "Speak with one voice," like Moses did before God to communicate with him. Definition: The Hebrew term "fi2" occurs 6 times in the Bible, often in verses describing the relationship between Moses and God. The word is used metaphorically as a sign of unity or unification of people (as seen in Exodus 19:5-7), where they are united by the covenant of Moses. It's also used figuratively to describe a group working together harmoniously, like the Ten Commandments were "spoken" by Moses and God: "Speak with one voice, ye men of Israel; let not any man take away his neighbor's house." (Numbers 15:34) "The two tablets are an oath to each other. Speak with one voice." (Deuteronomy 29:26)
