David said, As Yahweh lives, Yahweh will strike him; or his day shall come to die; or he shall go down into battle and perish.
Saul had used his spear to attack David three times (cf. 1 Samuel 18:10; 1 Samuel 19:9-10; 1 Samuel 20:33). It was, therefore, an instrument of death. It was also the symbol of Saul’s rule, similar to a scepter (cf. 1 Samuel 22:6). Abishai’s viewpoint was carnal. He concluded that because God had given David the upper hand he should use it to do away with his rival (1 Samuel 26:8; cf. 1 Samuel 24:4). David had used similar words when he promised to kill Goliath (cf. 1 Samuel 17:46), as had Saul in describing how he would kill David with his spear (cf. 1 Samuel 18:11).
