A dart in the King James Bible is a thrown spear, and the verses where it appears are not gentle. Phinehas took “a javelin in his hand” to stop a sin in the camp. Saul hurled one at David as he played music. Joab “took three darts in his hand, and thrust them through the heart of Absalom.” Paul uses the word as a picture of the unseen battle, telling believers to take “the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.” That last sentence is in Ephesians 6:16.
4 verses
And when Phinehas, the son of Eleazar, the son of Aaron the priest, saw it, he rose up from among the congregation, and took a javelin in his hand;
And it came to pass on the morrow, that the evil spirit from God came upon Saul, and he prophesied in the midst of the house: and David played with his hand, as at other times: and there was a javelin in Saul's hand.
Then said Joab, I may not tarry thus with thee. And he took three darts in his hand, and thrust them through the heart of Absalom, while he was yet alive in the midst of the oak.
Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.
Matthew George Easton, 1897
An instrument of war; a light spear. “Fiery darts” (Eph. 6:16) are so called in allusion to the habit of discharging darts from the bow while they are on fire or armed with some combustible material. Arrows are compared to lightning (Deut. 32:23, 42; Ps. 7:13; 120:4).
