The first and most frequent use of the word rendered coal is a live ember, burning fuel. ( Proverbs 26:21 ) In ( 2 Samuel 22:9 2 Samuel 22:13 ) "coals of fire" are put metaphorically for the lightnings proceeding from God. ( Psalms 18:8 Psalms 18:12 Psalms 18:13 ; 140:10 ) In ( Proverbs 26:21 ) fuel not yet lighted is clearly signified. The fuel meant in the above passage is probably charcoal, and not coal in our sense of the word.
