Isaiah 50:1-3·~1 min
Israel’s Sin
The LORD asks for the divorce certificate by which He supposedly sent Zion away or the creditor to whom He sold her, only to answer that her separation has come through her own sins and transgressions. When He came there was no one to answer, yet His power to redeem is unchanged: He can dry up the sea, turn rivers into wilderness, and dress the heavens in blackness, proving that Israel's plight cannot be explained by any failure in Him.
T1his is what the LORD says: 2Why was no one there when I arrived? 3I clothe the heavens in black
Section summaryThe opening movement answers the implied accusation that the LORD has divorced or sold off His people by showing that their separation has come through their own transgressions. God reminds them that when He came no one answered, not because His hand had grown too short to redeem, but because the same power that dries seas and clothes heavens in black remains fully His.
Role in the chapterThis section clears God of covenant unfaithfulness and places the blame for estrangement squarely on Israel's sin.
