The number of lies told about God and the Sinai covenant is considered to be significant

 From a strictly Karaite/Tanakh-only perspective, the number of lies told about God and the Sinai covenant is considered to be significant. Karaites believe that the Oral Tradition and later Rabbinic Judaism have introduced numerous false teachings and interpretations that have deviated from the original message of the Tanakh.

Some of the key areas where Karaites see deception and distortion include:

• The concept of the Trinity and the divinity of Jesus Christ, which Karaites see as a clear contradiction of the Tanakh's monotheistic message.
• The idea of original sin and the notion that humanity is inherently sinful, which Karaites believe is not supported by the Tanakh.
• The concept of rabbinic authority and the idea that the Oral Tradition has equal or even greater authority than the Tanakh.
• The introduction of new holidays and festivals not mentioned in the Tanakh, such as Hanukkah.
• The alteration of the biblical calendar and the introduction of a new system of calculating the timing of festivals.

Karaites believe that these deceptions have had a profound impact on humanity, leading to:

• A distorted understanding of God's nature and character.
• A misunderstanding of the Sinai covenant and the terms of God's relationship with humanity.
• The development of a complex system of rabbinic law and tradition that has obscured the simplicity and clarity of the Tanakh.
• The division of humanity into different religious groups, each with their own interpretations and traditions.

Some key Tanakhic references that support the Karaite perspective include:

• Deuteronomy 4:2, 12:32, and 13:1, which warn against adding to or subtracting from the commandments of the Tanakh.
• Isaiah 8:20, which emphasizes the importance of testing all teachings against the Tanakh.
• Jeremiah 7:31 and 32:34, which condemn the introduction of new and foreign practices.

Overall, from a Karaite/Tanakh-only perspective, the impact of these deceptions has been to lead humanity away from a direct and unmediated relationship with God, and to obscure the simplicity and clarity of the Tanakh's message.
