Shmuel Bais 16:9 Meaning and Commentary

2 Samuel 16:9

Then said Abishai the son of Zeruiah unto the king
A sister's son of his, and a general in the army, who could not bear to hear the king abused in this manner:

why should this dead dog curse my lord the king?
be suffered to do it with impunity; a "dog" he calls him, because of his vileness and baseness, and because of his impudence, and on account of his reproachful and abusive language, aptly signified by the snarling and barking of a dog; and a "dead" dog, as being useless, detestable, and abominable:

let me go over, I pray thee, and take off his head;
go over the plain where David and his men were, to the hill on which Shimei was, and strike off his head with his sword; which he could easily do, and soon put an end to his cursing.

Shmuel Bais 16:9 In-Context

7 And thus said Shimei when he cursed, Come out, come out, thou ish hadamim and thou ish habeliyya’al;

8 Hashem hath returned upon thee all the dahm of the Bais Sha’ul, in whose place thou hast reigned; and Hashem hath delivered the meluchah (kingdom) into the yad Avshalom binecha; and, behold, thou art taken in thy ra’ah, because thou art an ish damim.

9 Then said Avishai Ben Tzeruyah unto HaMelech, Why should this kelev hamet (dead dog) curse adoni HaMelech? Let me go over, now and cut off his rosh.

10 And HaMelech said, What have I to do with you, ye Bnei Tzeruyah? So let him curse, because Hashem hath said unto him, Curse Dovid. Who shall then say, why hast thou done so?

11 And Dovid said to Avishai, and to all his avadim, Hinei, beni, which came forth from within me, seeketh my nefesh; how much more now may this Bin-Hayemini (Benjamite) do it? Let him alone, and let him curse; for Hashem hath bidden him.
