Saqar (H8265) and its noun form sheqer (H8267) are the primary Hebrew words for falsehood and deceit. While sheqer is more common, saqar as a verb emphasizes the active choice to deceive β a deliberate turning away from truth. It is the opposite of emeth (truth/faithfulness).
The ninth commandment prohibits bearing sheqer witness (Exodus 20:16). Proverbs pairs the saqar of lying lips with the abomination they are to God (Proverbs 12:22). The prophets thunder against those who prophesy sheqer β false visions β leading God's people astray. In a world drowning in information, the distinction between truth and saqar remains the prophetic front line.
