I Kings 1:51

When this was reported to Solomon, together with the prayer of Adonijah that the king would swear to him that he would not put him to death with the sword (אם before ימית, a particle used in an oath), he promised him conditional impunity: "If he shall be brave (בּן־חיל, vir probus), none of his hair shall fall to the earth," equivalent to not a hair of his head shall be injured (cf. Sa1 14:45); "but if evil be found in him," i.e., if he render himself guilty of a fresh crime, "he shall die."

In this chapter we have, I. David declining in his health (Kg1 1:1-4). II. Adonijah aspiring to the kingdom, and treating his party, in order to it (Kg1 1:5-10). III. Nathan and Bathsheba contriving to secure the succession to Solomon, and prevailing for an order from David for the purpose (v. 11-31). IV. The anointing of Solomon accordingly, and the people's joy therein (Kg1 1:32-40). V. The effectual stop this put to Adonijah's usurpation, and the dispersion of his party thereupon (Kg1 1:41-49). VI. Solomon's dismission of Adonijah upon his good behaviour (Kg1 1:50-53).
