Charles H. Spurgeon on Psalms 89:10

Thou hast broken Rahab in pieces as one that is slain. Egypt was crushed like a corpse beneath the chariot wheels of the destroyer: its pomp and glory were broken like the limbs of the dead in battle. Egypt was Israel's ancient foe, and its overthrow wits a theme to which devout minds constantly reverted, as to a subject fit for their most exulting songs. We, too, have seen our Rahab broken, our sins overthrown, and we cannot but unite in the ascription of praise unto the Lord. Thou hast scattered thine enemies with thy strong arm. Thy strength has strewn thy foes dead upon the plain, or compelled them to flee hither and thither in dismay. Jehovah has overthrown his enemies with his own right arm, unaided and alone. Proud Rahab, swelling in her fury like the sea, was utterly broken and scattered before the Lord of Hosts.
