The Lord here invited the nations to a trial where he would prove that he alone is God. They were defenseless as he declared that a king from the east (41:2) would crush Babylon, opening the way for Israel to return.
This taunt against idolatry was a response to God’s raising up of Cyrus; the nations hope to find protection in their idols.
These two prophecies of salvation for God’s servant Israel (41:8–13, 14–16) prepare for the first of the suffering servant songs (see study note on 42:1–4).
This trial scene develops the Lord’s case against idolatry. Idols are nothing but a human creation, whereas God is the Creator of all things. Idols cannot speak, act, accomplish anything, or save their worshipers.
