(2.) One unable to speak by reason of want of knowing what to say, or how to say it; what proper mode of address to use, or what reasons to allege in his own behalf (Pro_31:8).
(3.) One unwilling to speak (Psa_39:9). We have a remarkable instance of this venerating dumbness, or silence, in the case of Aaron (Lev_10:3), after Nadab and Abihu, his sons, were consumed by fire. "Aaron held his peace;" did not exclaim against the justice of God, I but saw the propriety of the divine procedure, and humbly acquiesced in it. Christ restored a man who was dumb from daemoniacal influence (Mat_9:32-33; Luk_11:14), and another who was both blind and dumb from the same cause (Mat_12:22). The man who was deaf and had an impediment in his speech (Mar_7:32-35), whom Christ restored, was not dumb, nor probably deaf by nature, but was one who had a natural impediment to enunciation, or who, having early lost his hearing, gradually lost much of his speech, and had become a stammerer. Such an impediment is either natural, arising from what is called a bos, or ulcer, by which any one is, as we say, tongue-tied, or brought on when, from an early loss of hearing, the membrane of the tongue becomes rigid and unable to perform its office.
