Spit; Spittle spit, spit'-l (yaraq, roq; (em)ptuo): Spitting in a person's face indicated gross contempt (Numbers 12:14, Deuteronomy 25:9, Job 30:10, Isaiah 50:6, Matthew 26:67, Matthew 27:30, etc.); when performed by an unclean person it produced defilement (Leviticus 15:8) which necessitated washing the clothes and a bath. When David allowed his spittle (rir) to run down over his beard, it was his purpose to behave like a lunatic (1 Samuel 21:13). "Till I swallow down my spittle" (Job 7:19) has the same import as the English "in the twinkling of an eye" (1 Corinthians 15:52). Spittle was used by our Lord in restoring sight and speech (Mark 7:33, John 9:6) as signifying His will to cure. It was a widespread belief that spittle, accompanied with magical formulas, possessed medicinal qualities. "Oil" possessed a similar virtue. (Mark 6:13, James 5:14).
