Qetar (ืงึฐืึทืจ) is an Aramaic noun meaning a knot, a joint, or an enigmatic problem โ literally "that which is knotted together." It appears in Daniel 5:6,16 where King Belshazzar is promised rewards to whoever can "untie the knots" (interpret the mysterious handwriting on the wall). The word captures the idea of divine mysteries that must be supernaturally loosed.
The qetar of the handwriting on the wall is a concentrated image of divine revelation meeting human incapacity. Belshazzar's wise men โ astrologers, Chaldeans, diviners โ cannot untie the knot. Only Daniel, the man "in whom is a spirit of the holy gods" (Daniel 5:11), can do so. This pattern repeats throughout Daniel: the king cannot open his own dreams; his professional interpreters fail; the man of God alone receives divine illumination.
Paul uses the Greek equivalent (mysterion) to describe the gospel as a divine qetar โ a mystery hidden for ages, now revealed in Christ (Romans 16:25-26; Ephesians 3:3-6). The knot of God's redemptive plan, tied before the foundation of the world, was untied at the cross โ where all the tangled threads of law, sin, judgment, and mercy were resolved in one climactic act.
