Isaiah 50:9

Behold, the Lord GOD will help me; who is he that shall condemn me? lo, they all shall wax old as a garment; the moth shall eat them up.

Behold, the Lord God will help me,.... This is repeated from Isaiah 50:7, See Gill on "Isaiah 50:7"; to show the certainty of it, the strength of his faith in it, and to discourage his enemies:

who is he that shall condemn me? make me out a wicked person {c}, prove me guilty, and pass sentence upon me, when thus acquitted and justified by the Lord God? The Apostle Paul seems to have some reference to this passage in Romans 8:33,

lo, they all shall waste old as doth a garment; his enemies, those that accused him, the Scribes, Pharisees, and chief priests; and those that condemned him, the Jewish sanhedrim, and the Roman governor:

the moth shall eat them up; they shall be like a worn out or motheaten garment, that can never be used more. The phrases denote how secret, insensible, and irrecoverable, their ruin should be, both in their civil and church state, all being abolished and done away.
