The palate or roof of the mouth, and by extension, the faculty of taste and discernment. Used literally and figuratively for spiritual discernment.
Chek bridges the physical and spiritual senses. Job 12:11: 'Doth not the ear try words? and the mouth taste his meat?' The Psalmist exclaims, 'How sweet are thy words unto my taste!' (Psalm 119:103). Knowing God is experiential, sensory, intimate.
