حَتَّىٰٓ إِذَا بَلَغَ مَغْرِبَ ٱلشَّمْسِ وَجَدَهَا تَغْرُبُ فِى عَيْنٍ حَمِئَةٍ وَوَجَدَ عِندَهَا قَوْمًا ۗ قُلْنَا يَٰذَا ٱلْقَرْنَيْنِ إِمَّآ أَن تُعَذِّبَ وَإِمَّآ أَن تَتَّخِذَ فِيهِمْ حُسْنًا

Commentary:
The words مغرب الشمس i.e. the place where the sun set; signify the westernmost parts of Cyrus’ Empire or the north-western boundary of Asia Minor and refer to the Black Sea because it formed the north-western boundary of the Empire of Cyrus. The verse refers to the expedition which Cyrus undertook against his enemies in the west. "Soon after the conquest of the Median empire Cyrus was attacked by a coalition of the other powers of the East-Babylon, Egypt and Lydia, joined by Sparta, the greatest military power of Greece. In the spring of 546 Croesus of Lydia began the attack and advanced into Cappadocia, while the other powers were still gathering their troops. But Cyrus anticipated them; he defeated Croesus and followed him to his capital. In the autumn of 546 Sardis was taken and the Lydian kingdom became a province of the Persians… During the next few years the Persian army suppressed a rebellion of the Lydian. The King of Cilicia voluntarily acknowledged the Persian supremacy "(Enc. Brit., & Historians’ History of the World, under Cyrus).
The words, "he found it (the sun) setting in a spring of murky water," signify that it is not a small pool to which they refer. The waters referred to are so extensive that if one were to take his stand on the shore at the time of sunset, the sun would appear to be setting in the sea.
