Some have supposed this to be a challenge to the worshippers of idols; but I humbly conceive, that as these verses follow the account of Him, of whom Jehovah speaketh so gloriously, it is rather a demand, in reference to gospel days, to bring forth the blind and the deaf, spiritually considered, to whom the Lord Jesus would give the restoration of their faculties, in virtue of his great redemption; and as the heathen world are called in to behold the testimony, is not this a plain allusion to the conversion of the Gentiles? Isaiah 49:6.

8 Bring forth the blind people that have eyes, and the deaf that have ears.
9 Let all the nations be gathered together, and let the people be assembled: who among them can declare this, and shew us former things? let them bring forth their witnesses, that they may be justified: or let them hear, and say, It is truth.
