The Hebrew word mârach, represented by H4799, is a primitive root meaning to soften by rubbing or pressure. It is used medicinally to refer to the application of an emollient or the laying of a plaister. This highly specific term appears only 1 times in 1 unique verses in the entire Bible, highlighting its specialized use.
The sole appearance of H4799 is in Isaiah 38:21, which records a command given by the prophet Isaiah. In this context, Isaiah instructs that a lump of figs be taken and laid for a plaister upon a boil. This action is prescribed as the remedy that will lead to recovery. The use of the word emphasizes the specific, physical act of applying a poultice as a means of healing.
Several related words from its biblical context illuminate the meaning of H4799:
- H1690 dᵉbêlâh (a cake of pressed figs): This is the substance being applied. While used here medicinally Isaiah 38:21, it is also mentioned elsewhere as a food source 1 Samuel 25:18.
- H7822 shᵉchîyn (inflammation, i.e. an ulcer; boil, botch): This is the affliction being treated. It is described as a sore boil in the case of Job Job 2:7 and as a plague upon the Egyptians Exodus 9:9.
- H2421 châyâh (to live, whether literally or figuratively; causatively, to revive): This is the intended result of applying the plaister. The word is used for both physical recovery Isaiah 38:21 and for God's power to revive the spirit Isaiah 57:15.
The use of H4799 in scripture illustrates several key themes, even in its single occurrence.
- Healing Through Physical Means: The command from Isaiah shows God working through tangible, physical remedies. The healing is a result of a direct command followed by a practical action Isaiah 38:21.
- The Importance of Action: The word itself implies a deliberate application—softening by rubbing or pressure. This underscores that the healing process required a specific, hands-on act of care.
- Divine Authority over Life and Health: The context links the physical act of applying a poultice to the ultimate power of God to grant life and recovery. God declares, "I kill, and I make alive" Deuteronomy 32:39, and the recovery from the boil is a direct fulfillment of his prophet's word.
In summary, H4799 is a rare and precise term for applying a medicinal plaister. Its single use provides a powerful illustration of faith combined with action. It shows God's healing power being administered through a physical medium, demonstrating that divine intervention can work in concert with the tangible world to bring about restoration and life.
