Behold, they belch out with their mouth,.... Bark like dogs, so Aben Ezra; or "bubble out" , as a fountain bubbles out with water; so they cast out their wickedness in great abundance; see Jer 6:7; the phrase denotes the abundance of evil things and wicked speeches that came out of their mouths, which showed the naughtiness of their hearts; so David's enemies blustered and threatened what they would do to him could they find him; and Christ's enemies poured out their wicked charges of blasphemy and sedition against him, in great plenty, and without proof;swords [are] in their lips; the words of their lips were like sharp swords; see Ps 55:21; threatening the most severe and cruel things: or, besides their lips, and what they belched out with their mouths, they took swords in their hands in a literal sense; as Saul's messengers did to kill David, and as Judas and his band of men, who came to take Christ as a thief, with swords and staves, Mt 26:55;for who, [say they], doth hear?
what they uttered with their mouths and lips, in a blustering and threatening manner; though they were overheard by men, who carried what they said and designed to do to Michal, David's wife. The meaning may be, they would say what they pleased, and did not care who heard them, having nothing to fear from any, they having their orders from the king; see Ps 12:4; and so the Targum,"behold they belch out with their mouths words which are sharp as swords, and with their lips saying, we shall prevail; for who is he that hears, and can punish?'
'Aben Ezra's note is,"they thought that God did not hear their counsels;''and therefore the next words are in direct opposition to them; but so to think is monstrous stupidity and brutishness, Ps 94:4; some take the words to be the words of David, complaining that the civil magistrate, none of the judges, took notice of or punished such who belched out their lies and calumnies against him, saying, "for who doth hear?"
no man.
